Description
Oppfinnelsen angår festeanordninger til sammenføyning av gjenstander. Nærmere bestemt angår oppfinnelsen termoplast-festeanordninger for sammenføyning av gjenstander, og særlig fiberarmerte termoplastkomposittfesteanor dninger. The invention relates to fastening devices for joining objects. More specifically, the invention concerns thermoplastic fastening devices for joining objects, and in particular fibre-reinforced thermoplastic composite fastening devices.
i Det er tidligere kjent en rekke plastfesteanordninger som benyttes i kombinasjon med varme for sammenføyning av gjenstander- Noen av disse festeanordninger omfatter fiberarmerte materialer. In the past, a number of plastic fastening devices are known which are used in combination with heat to join objects together. Some of these fastening devices include fibre-reinforced materials.
For eksempel er der i US-PS 4 478 544 beskrevet en kompositt-nagle som har en grunnmasse av herdeplast med karbonfiber-armering. Naglen anbringes gjennom forformede hull i to plater som skal sammenføyes, og deretter blir et utvidet hode dannet på naglen ved anvendelse av varme og trykk. For example, US-PS 4 478 544 describes a composite rivet which has a base mass of thermosetting plastic with carbon fiber reinforcement. The rivet is placed through preformed holes in two plates to be joined, and then an enlarged head is formed on the rivet by the application of heat and pressure.
Det er også kjent at piastfesteanordninger kan deformeresIt is also known that piast fasteners can be deformed
ved bruk av ultralydvarmeapparater, som vist i US-PSusing ultrasonic heaters, as shown in US-PS
3 499 808. 3,499,808.
Kjent teknikk omfatter spisse piastfesteanordninger såsom kramper, slik det er vist i US-PS 4 281 785. Plastkrampene i henhold til dette patentskrift er ikke armert. Krampene drives gjennom lag av tøy og varmes deretter opp for å føye sammen krampens to ben og holde dem på plass. Known art includes pointed piast fastening devices such as crampons, as shown in US-PS 4,281,785. The plastic crampons according to this patent are not reinforced. The cramp is driven through layers of cloth and then heated to join the cramp's two legs and hold them in place.
US-PS 4 478 661 beskriver bruken av termoplasttråd eller termoplastkramper for å føye sammen termoplastplater. US-PS 4,478,661 describes the use of thermoplastic wire or thermoplastic staples to join thermoplastic sheets.
US-PS 4 582 236 angir bruken av stifter eller kramper av syntetisk harpiks som drives gjennom forformede hull i til-støtende plater av materiale og deretter varmes opp for dannelse av naglehoder. US-PS 4,582,236 discloses the use of staples or staples of synthetic resin which are driven through preformed holes in adjacent sheets of material and then heated to form rivet heads.
i I alle de eksempler som er angitt ovenfor, blir festeanordningen enten plassert gjennom et forformet hull, eller en spiss festeanordning drives gjennom et forholdsvis føyelig materiale uten anvendelse av noe varme på forhånd. De fremgangsmåter som er beskrevet i henvisningene ovenfor, er In all the examples given above, the fastener is either placed through a preformed hole, or a pointed fastener is driven through a relatively pliable material without the application of any heat beforehand. The methods described in the references above are
ikke egnet til sammenføyning av gjenstander der hvor en av gjenstandene er en termoplastgjenstand som ikke har et forformet hull for mottagning av festeanordningen og som har tilstrekkelig tykkelse og styrke til at en festeanordning ikke lett kan drives gjennom. Den foreliggende oppfinnelse skaffer imidlertid fremgangsmåter og festeanordninger rettet på nettopp en slik situasjon. not suitable for joining objects where one of the objects is a thermoplastic object which does not have a pre-formed hole for receiving the fastening device and which has sufficient thickness and strength that a fastening device cannot be easily driven through. The present invention, however, provides methods and fastening devices aimed at just such a situation.
Festingen av fiberarmerte komposittmaterialer for luftfart-industrien krever festeanordninger og festemetoder som gir lav vekt, høy skjærmotstand og en lav spenning for komposittmaterialet. Den foreliggende oppfinnelse skaffer en fiberarmert nagle eller spiker og fremgangsmåte til anvendelse av denne som skaffer de ønskede egenskaper. Videre kan naglen låses på plass ved en smeltebinding med komposittmaterialet. The fastening of fibre-reinforced composite materials for the aviation industry requires fastening devices and fastening methods that provide low weight, high shear resistance and a low stress for the composite material. The present invention provides a fiber-reinforced rivet or nail and method for using this which provides the desired properties. Furthermore, the rivet can be locked in place by a fusion bond with the composite material.
Fremgangsmåten i en foretrukket utførelsesform omfatter de trinn hvor en første termoplastgjenstand plasseres mot en annen termoplastgjenstand, og tilstøtende partier av den første og annen gjenstand deretter varmes opp. Deretter blir en spiss ende av en termoplastfesteanordning drevet gjennom de oppvarmede områder på den første og annen gjenstand, og de oppvarmede områder blir deretter tillatt å avkjøle, hvilket låser festeanordningen til den første og annen gjenstand. De halvt smeltede oppvarmede områder på The method in a preferred embodiment comprises the steps where a first thermoplastic object is placed against another thermoplastic object, and adjacent parts of the first and second object are then heated. Then, a pointed end of a thermoplastic fastener is driven through the heated areas of the first and second objects, and the heated areas are then allowed to cool, locking the fastener to the first and second objects. The semi-melted heated areas on
den første og annen gjenstand smelter sammen med termoplastfesteanordningen ved avkjøling av de oppvarmede områder, selv om ikke noen ytterligere varme anvendes på endene av festeanordningen for dannelse av et utvidet hode eller lignende. Fremgangsmåten kan imidlertid også omfatte trinn hvor man senere varmer opp endene på festeanordningen og danner utvidede hoder derpå. the first and second objects fuse with the thermoplastic fastener upon cooling of the heated areas, although no additional heat is applied to the ends of the fastener to form an enlarged head or the like. However, the method can also include steps where the ends of the fastening device are later heated and extended heads are formed thereon.
Festeanordningen selv er fortrinnsvis en fiberarmert festeanordning som omfatter en rekke kontinuerlige, stort sett parallelle armeringsfilamenter i en grunnmasse av termoplastmateriale som avgrenser en langstrakt form som er spisset ved en ende. The fastening device itself is preferably a fibre-reinforced fastening device which comprises a number of continuous, largely parallel reinforcing filaments in a base mass of thermoplastic material which defines an elongated shape which is pointed at one end.
En rekke gjenstander, trekk og fordeler ved den foreliggende oppfinnelse vil være åpenbare for fagfolk ved lesning av den følgende angivelse sett i sammenheng med den ledsagende tegning. A number of objects, features and advantages of the present invention will be apparent to those skilled in the art upon reading the following specification taken in conjunction with the accompanying drawings.

Fig. 9 viser en annen alternativ utførelses form for anvendelse av den foreliggende oppfinnelse hvor et enkelt lag av termoplastmateriale er blitt forbundet med et ikke-termoplastisk underliggende underlag. Fig. 10 og 11 er lignende fig. 4 og 5 og representerer en annen alternativ utførelsesform for anvendelse av den foreliggende oppfinnelse. In fig. 8 is the pointed end of the nail according to fig. 7 has been heated and formed into an extended head which abuts the lower plate of the thermoplastic material. Fig. 9 shows another alternative embodiment for the application of the present invention where a single layer of thermoplastic material has been connected to a non-thermoplastic underlying substrate. Fig. 10 and 11 are similar fig. 4 and 5 and represents another alternative embodiment for use of the present invention.
På fig. 10 er en termoplastisk spiker eller nagle med etIn fig. 10 is a thermoplastic nail or rivet with a
utvidet hode i den ene ende og et spisst punkt i den annen ende blitt drevet gjennom det oppvarmede parti i en øvre termoplastplate og gjennom et forformet hull i en nedre metallplate. extended head at one end and a pointed point at the other end have been driven through the heated portion of an upper thermoplastic sheet and through a preformed hole in a lower metal sheet.
På fig. 11 er den spisse, nedre ende av spikeren ifølgeIn fig. 11 is the pointed, lower end of the nail according to
fig. 10 blitt varmet opp og dannet til et utvidet hode som slutter opp til den nedre plate av metallisk materiale. fig. 10 has been heated and formed into an extended head which joins up to the lower plate of metallic material.
Under henvisning nå til fig. 1-5 skal den foretrukne fremgangsmåte for sammenføyning av termoplastgjenstander ved bruk av festeanordningen i henhold til oppfinnelsen beskrives. Referring now to fig. 1-5, the preferred method for joining thermoplastic objects using the fastening device according to the invention shall be described.
På fig. 1 er en første plate av fiberarmert termoplastmateriale 10 blitt lagt oppå en annen plate 12 som kan være termoplastisk eller av et hvilket som helst annet materiale såsom metall. Platene 10 og 12 kan generelt betegnes som en første og annen gjenstand. En grenseflate 11 er avgrenset der hvor platen 10 kommer i kontakt med platen 12. In fig. 1, a first plate of fibre-reinforced thermoplastic material 10 has been placed on top of another plate 12 which may be thermoplastic or of any other material such as metal. The plates 10 and 12 can generally be described as a first and second object. An interface 11 is defined where the plate 10 comes into contact with the plate 12.
Omønskelig kan hver av platene såsom plate 10 omfatte en termoplastisk grunnmasse 14 med en rekke armeringsfibre såsom 16 og 18, som holdes i grunnmassen 14. Fibrene 16 og 18 kan omfatte en vevet duk av stofftype-armeringsmateriale. Alternativt kan fibrene være i form av en tilfeldig matte med forholdsvis lange fibre som ligger stort sett flatt i planet av platen 10 i en ellers tilfeldig orientering. Optionally, each of the plates such as plate 10 may comprise a thermoplastic matrix 14 with a number of reinforcing fibers such as 16 and 18, which are held in the matrix 14. The fibers 16 and 18 may comprise a woven cloth of fabric-type reinforcing material. Alternatively, the fibers can be in the form of a random mat with relatively long fibers which lie largely flat in the plane of the plate 10 in an otherwise random orientation.
Som det fremgår av fig. 1, ligger armeringsfibrene 16 og 18 stort sett parallelt med planet av platen 10. For å lette illustrasjonen av andre trekk ved oppfinnelsen er armeringsfibrene såsom 16 og 18 i lagene 10 og 12, slik det er vist på fig. 1, ikke vist i de resterende figurer. As can be seen from fig. 1, the reinforcing fibers 16 and 18 lie largely parallel to the plane of the plate 10. To facilitate the illustration of other features of the invention, the reinforcing fibers such as 16 and 18 in the layers 10 and 12, as shown in fig. 1, not shown in the remaining figures.
Fig. 2 viser trinnet ved oppvarming av partiene 20 og 22 påFig. 2 shows the step of heating the parts 20 and 22 on
den første og annen plate 10 og 12 i nærheten av grenseflaten 11. Dette utføres fortrinnsvis ved plassering av et varme-element 24 av en ultralyd-varmepistol 26 mot den øvre flate 28 på den øvre termoplastplate 10 for å varme opp bare et lite område under denne. Varmeelementet 24 holdes på plass mot platen 10 i et tilstrekkelig tidsrom til å varma opp partiene 20 og 22, og deretter blir varmeelementet 24 fjernet. the first and second plates 10 and 12 near the interface 11. This is preferably carried out by placing a heating element 24 of an ultrasonic heat gun 26 against the upper surface 28 of the upper thermoplastic plate 10 to heat only a small area below this. The heating element 24 is held in place against the plate 10 for a sufficient period of time to heat up the parts 20 and 22, and then the heating element 24 is removed.
Oppvarmingen av partiene 20 og 22 kan generelt beskrivesThe heating of parts 20 and 22 can be generally described
som oppvarming av partiene 20 og 22 tilstrekkelig til åas heating the lots 20 and 22 sufficiently to
mykne dem. Dersom det spesielle materiale som er involvert har et skarpt avgrenset smeltepunkt, kan det være foretrukket, skjønt ikke nødvendig, å varme opp dette materiale til en temperatur som er høyere enn dets smeltepunkt. soften them. If the particular material involved has a sharply defined melting point, it may be preferred, although not necessary, to heat this material to a temperature higher than its melting point.
Som vist på fig. 3 blir et lengdestykke av termoplastfestemateriale 30, fortrinnsvis med en spiss nedre ende 32, drevet eller plassert gjennom de oppvarmede partier 20 og 22 i den første og annen gjenstand 10 og 12. Dersom en av platene såsom plate 12 er av metall eller et annet ikke-plast-materiale, kan det være nødvendig å danne et hull i platen 12, gjennom hvilket festematerialet 30 kan mottas, se f.eks. den alternative utførelsesform på fig 10 og 11 som angitt nedenunder. As shown in fig. 3, a length of thermoplastic fastener material 30, preferably with a pointed lower end 32, is driven or placed through the heated portions 20 and 22 in the first and second objects 10 and 12. If one of the plates such as plate 12 is of metal or another is not -plastic material, it may be necessary to form a hole in the plate 12, through which the fastening material 30 can be received, see e.g. the alternative embodiment of figures 10 and 11 as indicated below.
Som vist på fig. 3 blir stykket av festemateriale 30 konstru ert fra en termoplastgrunnmasse 34 som har en rekke stort sett parallelle armeringsfilamenter 36 deri, orientert parallelle med lengden av festematerialet~30 og kontinuerlige over festeanordningens lengde. Det foretrekkes, men er ikke nødvendig, at termoplastgrunnmassen 34 i festematerialet 30 konstrueres av samme type termoplastmateriale som platene 10 og 12. Det skal bemerkes at selv når platene 10 og 12 og festeanordningen 34 benytter den samme type termoplastmateriale, f.eks. polyfenylensulfid, kan der være en viss variasjon i egenskapene på grunn av forskjellige formingsprosesser som platene og festematerialet er blitt underkastet. As shown in fig. 3, the piece of fastener material 30 is constructed from a thermoplastic matrix 34 having a series of generally parallel reinforcing filaments 36 therein, oriented parallel to the length of the fastener material 30 and continuous over the length of the fastener. It is preferred, but not necessary, that the thermoplastic base mass 34 in the fastening material 30 is constructed from the same type of thermoplastic material as the plates 10 and 12. It should be noted that even when the plates 10 and 12 and the fastening device 34 use the same type of thermoplastic material, e.g. polyphenylene sulphide, there may be some variation in the properties due to different forming processes to which the plates and fixing material have been subjected.
Slik det best kan ses på fig. 6, som er et grunnriss med et snitt langs linje 6-6 på fig. 3, er materialstykket 30 fortrinnsvis sylindrisk og har et tverrsnittsareal som er litt mindre enn de oppvarmede områder 20 og 22. As can best be seen in fig. 6, which is a plan with a section along line 6-6 in fig. 3, the piece of material 30 is preferably cylindrical and has a cross-sectional area that is slightly smaller than the heated areas 20 and 22.
Som vist på fig. 4, når man benytter stykket av festemateriale 30, blir materialet 30 kuttet eller på annen måte avskåret på en side av den første og annen plate 10 og 12 på motsatt side av den spisse ende 32 for derved å avgrense en annen ende 38 av en avkuttet festeanordning 40 som rager gjennom den første og annen plate 10 og 12. Festeanordningen 40 kan generelt betegnes som en spiker eller nagle 40. As shown in fig. 4, when using the piece of fastening material 30, the material 30 is cut or otherwise severed on one side of the first and second plates 10 and 12 opposite the pointed end 32 to thereby define another end 38 of a cut fastening device 40 which projects through the first and second plates 10 and 12. The fastening device 40 can generally be described as a nail or rivet 40.
Det er mulig å avslutte prosessen på dette punkt, idet man tillater de oppvarmede partier 20 og 22 i den første og annen gjenstand og avkjøle, hvilket fester spikeren 40 på plass som vist på fig. 4. På grunn av den halvsmeltede tilstand av de oppvarmede partier 20 og 22 når spikeren 40 It is possible to terminate the process at this point, allowing the heated portions 20 and 22 of the first and second articles to cool, securing the nail 40 in place as shown in FIG. 4. Due to the semi-molten state of the heated portions 20 and 22, the nail 40
først drives gjennom, blir en ytre flate 42 på spikeren 40 også myknet i noen tid slik at ved avkjøling blir spikeren 40 festet til det termoplastiske grunnmassemateriale i platene 10 og 12. is first driven through, an outer surface 42 of the nail 40 is also softened for some time so that upon cooling the nail 40 is attached to the thermoplastic base material in the plates 10 and 12.
Nærmere bestemt, dersom de oppvarmede partier 20 og 22 er blitt varmet opp til over.smeltepunktet for det termoplastiske grunnmassemateriale i platene 10 og 12, vil den ytre flate 42 i spikeren 40 generelt også være smeltet slik at der foreligger faktisk sammensmelting av den ytre flate 42 i spikeren 40 med det termoplastiske grunnmassemateriale i platene 10 og 12. More specifically, if the heated portions 20 and 22 have been heated above the melting point of the thermoplastic base material in the plates 10 and 12, the outer surface 42 of the nail 40 will generally also be melted so that there is actual fusion of the outer surface 42 in the nail 40 with the thermoplastic matrix material in the plates 10 and 12.
Det kan således være ønskelig i noen tilfeller at plastgrunn-massen 34 i festematerialet 30 har et lavere smeltepunkt eller mykningspunkt enn det materiale som danner grunnmassen i platene 10 og 12. Videre kan det være ønskelig å forsyne festematerialet 30 med en ru ytre flate for ytterligere holdestyrke. Avkjølingen kan utføres forholdsvis hurtig ved at man tillater platene 10 og 12 å kjølne under omgivende atmosfæriske betingelser. It may thus be desirable in some cases that the plastic base mass 34 in the fastening material 30 has a lower melting point or softening point than the material that forms the base mass in the plates 10 and 12. Furthermore, it may be desirable to provide the fastening material 30 with a rough outer surface for additional holding power. The cooling can be carried out relatively quickly by allowing the plates 10 and 12 to cool under ambient atmospheric conditions.
Skjønt, i mange anvendelser, styrken av forbindelsen mellom platene 10 og 12 som skaffes av spikeren 40 som vist på Although, in many applications, the strength of the connection between the plates 10 and 12 provided by the nail 40 as shown in
fig. 4 kan være tilstrekkelig, kan valgfritt den spisse ende 30 og den annen ende 38 på spikeren 40 varmes opp for å mykne dem, og deretter kan endene 32 og 38 etterformes for dannelse av utvidede naglehoder 44 og 46 som selv vil være sammensmeltet med platene henholdsvis 10 og 12. De utvidede hoder 44 og 46 kan f.eks. dannes med ultralydopp-varmede, hodedannende matriser 48 og 50 som vist på fig. 5. Oppvarmingsmatrisene 48 og 50 kommer i inngrep med endene 38 og 32 på spikeren 40 i henhold til fig. 4, og trykk og varme anvendes derpå for å mykne endene 38 og 32 og deretter deformere dem til den form som er vist på fig. 5. Deretter blir varmematrisene 48 og 50 fjernet. fig. 4 may be sufficient, optionally the pointed end 30 and the other end 38 of the nail 40 can be heated to soften them, and then the ends 32 and 38 can be reshaped to form enlarged nail heads 44 and 46 which will themselves be fused to the plates respectively 10 and 12. The extended heads 44 and 46 can e.g. is formed with ultrasonically heated, head-forming dies 48 and 50 as shown in fig. 5. The heating dies 48 and 50 engage the ends 38 and 32 of the nail 40 according to FIG. 4, and pressure and heat are then applied to soften the ends 38 and 32 and then deform them to the shape shown in FIG. 5. Next, the heating matrices 48 and 50 are removed.
Det skal forstås at den fremgangsmåte som er beskrevet ovenfor, lett kan tilpasses en automatisk fremgangsmåte for innsetting av en rekke festeanordninger i likhet med festeanordningen 40 gjennom platene 10 og 12. It should be understood that the method described above can easily be adapted to an automatic method for inserting a series of fastening devices similar to the fastening device 40 through the plates 10 and 12.
I en utførelsesform vil stykket av termoplastfestemateriale 30 ha sin nedre ende som ble skilt fra festeanordningen 40 spisset på nytt, og ultralydvarmeapparatet 26 flyttes for lokalt å varme opp et annet område på platene 10 og 12, og In one embodiment, the piece of thermoplastic fastener material 30 will have its lower end that was separated from the fastener 40 repointed, and the ultrasonic heater 26 moved to locally heat another area of the plates 10 and 12, and
festeprosessen vil bli gjentatt.the attachment process will be repeated.
Den nedre ende av stykket av festemateriale 30 kan spisses mekanisk med en innretning såsom en blyantspisser eller en roterende slipemaskin. The lower end of the piece of fastening material 30 can be sharpened mechanically with a device such as a pencil sharpener or a rotary sharpener.
Den foreliggende oppfinnelse er spesielt utviklet for bruk med komposittmaterialer med høy styrke som kan anvendes ved høy temperatur, f.eks. materialer konstruert fra en grunnmasse av polymermateriale fra polyarylensulfidfamilien. Polyarylen-sulfider er en familie av aromatiske sulfidpolymerer som har den generelle formel (AR-X-AR-X)n. Den aromatiske enhet kan være en mono- eller polycyklisk molekyldel, og X kan velges fra minst én av gruppene 0, S, SO2, CO, 0C0, NCHO The present invention has been specially developed for use with composite materials with high strength which can be used at high temperature, e.g. materials constructed from a base mass of polymeric material from the polyarylene sulphide family. Polyarylene sulfides are a family of aromatic sulfide polymers having the general formula (AR-X-AR-X)n. The aromatic unit can be a mono- or polycyclic molecular moiety, and X can be selected from at least one of the groups 0, S, SO2, CO, 0C0, NCHO
etc. Generelt er disse polymerer kjent for sin utmerkede kjemiske bestandighet, god termisk stabilitet og fysisk styrke. etc. In general, these polymers are known for their excellent chemical resistance, good thermal stability and physical strength.
Det enkleste medlem av polyarylensulfidfamilien som ble benyttet i eksemplene angitt nedenunder, er polyfenylensulfid som består av en polymerryggrad av vekslende fordelte aromatiske ringer og toverdige svovelatomer. Polyfenylensulfid er en i handelen tilgjengelig termoplastharpiks for konstruk-sjonsformål, som er semi-krystallinsk av natur med en glass-temperatur på 85°C og et krystallinsk smeltepunkt på 285°C. The simplest member of the polyarylene sulfide family used in the examples set forth below is polyphenylene sulfide, which consists of a polymer backbone of alternating aromatic rings and divalent sulfur atoms. Polyphenylene sulfide is a commercially available thermoplastic resin for construction purposes, which is semi-crystalline in nature with a glass transition temperature of 85°C and a crystalline melting point of 285°C.
Den termoplastiske festeanordning 40 er fortrinnsvis en med karbonfiber eller glassfiber armert pultrudert komponent dannet ved trekking av kontinuerlige stry av karbonfibre eller glassfibre impregnert med pulverisert polyfenylensulfid gjennom en oppvarmet formingsmatrise for å konsolidere termoplastmaterialet og danne polyfenylensulfidgrunnmassen 34 The thermoplastic fastener 40 is preferably a carbon fiber or glass fiber reinforced pultruded component formed by drawing continuous strands of carbon fibers or glass fibers impregnated with powdered polyphenylene sulfide through a heated forming die to consolidate the thermoplastic material and form the polyphenylene sulfide matrix 34

De enkelte fibre i stryene eller filamentene 36 vil generelt være kontinuerlige over hele lengden av festematerialet 30, som kan være mange centimeter langt. Fremgangsmåter til fremstilling which surrounds the reinforcing carbon fiber filaments 36. Preferably, the fastening material 30 has a carbon fiber content that is in the range from approx. 50 to approx. 75 percent by weight. The individual fibers in the strings or filaments 36 will generally be continuous over the entire length of the fastening material 30, which can be many centimeters long. Methods of manufacture

Et annet medlem av polyarylensulfidfamilien som foretrekkes for bruk i den foreliggende oppfinnelse, er polyfenylensulfidsulfon. Polyfenylensulfidsulfon kan fremstilles på den måte som er beskrevet i US-PS 4 301 274. Dette er et amorft materiale som ikke har noe skarpt avgrenset krystallinsk smeltepunkt. Når den første og annen gjenstand 10 og 12 konstrueres"fra polyfenylensulfidsulfon, varmes de opp til et punkt som er tilstrekkelig til å mykne dem slik at spikeren 40 kan drives gjennom. Fortrinnsvis har polyfenylensulfidsulfon-plater 10 og 12 områdene 20 og 22 varmet opp til en temperatur i området 320-370°C. Another member of the polyarylene sulfide family preferred for use in the present invention is polyphenylene sulfide sulfone. Polyphenylene sulphide sulphone can be prepared in the manner described in US-PS 4 301 274. This is an amorphous material which has no sharply defined crystalline melting point. When the first and second articles 10 and 12 are constructed from polyphenylene sulfide sulfone, they are heated to a point sufficient to soften them so that the nail 40 can be driven through. Preferably, polyphenylene sulfide sulfone sheets 10 and 12 have regions 20 and 22 heated to a temperature in the range 320-370°C.
Eksempel 1Example 1
Den første og annen plate 10 og 12 av polyfenylensulfid-materialet armert med stampet glassfiber og med en tykkelse på ca. 1,65 mm ble plassert mot hverandre som vist på fig. 1. En pultrudert karbonfiberarmert polyfenylensulfid-stang med en diameter på 6,35 mm ble spisset ved en ende. Lokaliserte områder 20 og 22 med en diameter på ca. 9,5 mm ble varmet opp med et ultralydvarmeapparat inntil de var i en halvsmeltet, myknet tilstand. Områdene 20 og 22 ble varmet opp til en temperatur på 300-350°C. Varmeapparatet ble deretter fjernet, og den spissede stang ble drevet gjennom de oppvarmede områder 20 og 22 med en hammer. Ved avkjøling av platene 10 og 12 ble det observert at spikeren 40 var låst på plass på grunn av termoplastisk smelting og re-stivning, dvs. sammensmelting, ved berøringen av den ytre overflate 42 på spikeren 40 med platene 10 og 12. The first and second plates 10 and 12 of the polyphenylene sulphide material reinforced with stamped glass fiber and with a thickness of approx. 1.65 mm were placed against each other as shown in fig. 1. A 6.35 mm diameter pultruded carbon fiber reinforced polyphenylene sulfide rod was tapered at one end. Localized areas 20 and 22 with a diameter of approx. The 9.5 mm was heated with an ultrasonic heater until it was in a semi-molten, softened state. Areas 20 and 22 were heated to a temperature of 300-350°C. The heater was then removed and the pointed rod was driven through the heated areas 20 and 22 with a hammer. Upon cooling the plates 10 and 12, it was observed that the nail 40 was locked in place due to thermoplastic melting and re-solidification, i.e. fusion, at the contact of the outer surface 42 of the nail 40 with the plates 10 and 12.
Eksempel 2Example 2
En karbonfiberarmert pultrudert polyfenylensulfid-stang med en diameter på 6,35 mm i likhet med den som er beskrevet i eksempel 1 ble spisset til et punkt. En ultralydpistol ble brukt til lokalt å varme opp et ca. 9,5 mm i diameter område av en glassfiberarmert polyfenylensulfid-komposittplate ca. 6,35 mm tykk inntil den ble myknet. Platen ble varmet opp til en temperatur i området 300-350°C. Ved fjerning av ultralydvarmeapparatet ble denne spissede stang drevet gjennom det oppvarmede område med en hammer og deretter avkuttet ca. 6,35 mm over platens overflate. Ultralydapparatet ble deretter brukt til å smelte polyfenylensulfid-grunnmassen i den utoverragende stubb og stubben ble gjort flat og utvidet for å danne et sirkelformet hode med en større diameter enn stangens legeme. Samme oppvarmings- og utflatings-prosess ble deretter utført på den spisse ende som raget ut fra den motsatte side av platen. Naglen ble smeltet til platen på grunn av den termoplastiske smelting og re-stivning av de sylindriske kontaktflater på stangen og platen. Dessuten ble de utvidede hoder smeltet sammen med de øvre og nedre overflater av platen. A 6.35 mm diameter carbon fiber reinforced pultruded polyphenylene sulfide rod similar to that described in Example 1 was tapered to a point. An ultrasound gun was used to locally heat an approx. 9.5 mm in diameter area of a fiberglass-reinforced polyphenylene sulphide composite plate approx. 6.35 mm thick until softened. The plate was heated to a temperature in the range of 300-350°C. When removing the ultrasonic heater, this pointed rod was driven through the heated area with a hammer and then cut off approx. 6.35 mm above the plate surface. The ultrasonic apparatus was then used to melt the polyphenylene sulphide matrix into the protruding stump and the stump was flattened and expanded to form a circular head with a larger diameter than the body of the rod. The same heating and flattening process was then carried out on the pointed end protruding from the opposite side of the plate. The rivet was fused to the plate due to the thermoplastic melting and re-solidification of the cylindrical contact surfaces of the rod and plate. Also, the extended heads were fused to the upper and lower surfaces of the plate.

Alternativt, som vist på fig. 7 og 8, kan det fiberarmerte festemateriale skaffes i form av prefabrikerte spikre eller nagler 52 som har et forformet hode 54 med utvidet diameter som avgrenser én ende derav med et spisset punkt 56 avgrenset på den annen ende derav. Alternatively, as shown in fig. 7 and 8, the fiber-reinforced fastener may be provided in the form of prefabricated nails or rivets 52 having a preformed head 54 of enlarged diameter defining one end thereof with a pointed point 56 defined on the other end thereof.

Som tidligere beskrevet vil en ytre overflate 58 på spikeren 52 sammensmeltes med platene 10 og 12 ved deres kontaktflater med platene 10 og 12 innenfor de oppvarmede områder 20 og 22. As previously described, an outer surface 58 of the nail 52 will fuse with the plates 10 and 12 at their contact surfaces with the plates 10 and 12 within the heated areas 20 and 22.
Deretter kan den spissede nedre ende 56 på spikeren 52 varmes opp for å mykne den, og den kan deformeres på en måte som Then, the pointed lower end 56 of the nail 52 can be heated to soften it, and it can be deformed in a manner that

En annen alternativ utførelsesform av den foreliggende oppfinnelse er vist på fig. 9, hvor en enkelt plate 10 av termoplastmateriale er blitt festet til et ikke-termoplastisk underliggende underlag 64, som f.eks. kan være?t underlag av tre, med en termoplastspiker 52 i likhet med det som tidligere er beskrevet med hensyn til fig. 7. Another alternative embodiment of the present invention is shown in fig. 9, where a single plate 10 of thermoplastic material has been attached to a non-thermoplastic underlying substrate 64, such as e.g. can be a wooden substrate, with a thermoplastic nail 52 similar to what was previously described with respect to fig. 7.
Termoplastplaten 10 anbringes mot underlaget 64, og partiet 20 varmes opp med et ultralydapparat på samme måte som tidligere beskrevet under henvisning til fig. 2. The thermoplastic sheet 10 is placed against the substrate 64, and the part 20 is heated with an ultrasound device in the same way as previously described with reference to fig. 2.
Deretter drives termoplastspikeren 52 som har det forformede hode 54 som tidligere beskrevet med hensyn til fig. 7, med sin spisse ende 56 gjennom det oppvarmede parti 20 i platen 10 og inn i det underliggende treunderlag 64. Ved avkjøling av det oppvarmede parti 20 blir termoplastgjenstanden 10 låst til spikeren 52 ved sammensmelting derav med flaten 58 på spikeren 52. Dessuten holder det utvidede hode 54 på spikeren 52 platen 10 på plass mekanisk. Next, the thermoplastic nailer 52, which has the preformed head 54 as previously described with respect to fig. 7, with its pointed end 56 through the heated part 20 in the plate 10 and into the underlying wooden substrate 64. When the heated part 20 cools, the thermoplastic object 10 is locked to the nail 52 by fusing it with the surface 58 of the nail 52. Moreover, it holds extended head 54 of the nail 52 plate 10 in place mechanically.
Det skal forstås at med denne alternative utførelsesformIt should be understood that with this alternative embodiment
kan en spiker såsom spikeren 40 uten et forformet hode derpå benyttes, og kan på tilfredsstillende måte feste platen 10 til det underliggende underlag 64 selv uten for- eller etterforming av et utvidet hode på spikeren 40, ganske enkelt a nail such as the nail 40 without a preformed head thereon can be used, and can satisfactorily attach the plate 10 to the underlying substrate 64 even without preforming or postforming an extended head on the nail 40, simply
ved en låsemekanisme som kan skaffes ved sammensmelting av overflaten 42 og spikeren 40 med det oppvarmede område 20 by a locking mechanism which can be obtained by fusing the surface 42 and the nail 40 with the heated area 20

Alternativ utførelsesform i henhold til fig. 10 og 11Alternative embodiment according to fig. 10 and 11
En spesiell situasjon hvor den foreliggende oppfinnelse er nyttig for sammenføyning av en termoplastplate og en metallplate såsom aluminium eller titan, er i en ramme for et fly eller lignende anvendelse. A particular situation where the present invention is useful for joining a thermoplastic sheet and a metal sheet such as aluminum or titanium is in a frame for an aircraft or similar application.
På fig. 10 er en første termoplastplate 10 blitt lagt oppå en andre metallplate 70 med en åpning 72 dannet gjennom denne. Deretter blir det lille parti 20 på termoplastplaten 10 varmet opp med et ultralydapparat som tidligere er beskrevet under henvisning til fig. 2. In fig. 10, a first thermoplastic sheet 10 has been placed on top of a second metal sheet 70 with an opening 72 formed through this. Next, the small part 20 on the thermoplastic plate 10 is heated with an ultrasound device which was previously described with reference to fig. 2.
Deretter blir den spisse ende 56 av termoplastspikeren med det forformede hode 54 som tidligere beskrevet under henvisning til fig. 7 drevet gjennom det oppvarmede parti 20 i platen 10 og gjennom åpningen 72 i metallplaten 70. Ved avkjøling av det oppvarmede parti 20 blir termoplastplaten 10 låst til spikeren 52 ved sammensmelting derav med overflaten 58 på spikeren 52. Next, the pointed end 56 of the thermoplastic nail with the preformed head 54 as previously described with reference to fig. 7 driven through the heated part 20 in the plate 10 and through the opening 72 in the metal plate 70. When the heated part 20 cools, the thermoplastic plate 10 is locked to the nail 52 by fusing it with the surface 58 of the nail 52.
Det utvidede hode 60 blir deretter dannet på den spisse ende av spikeren 52 for å holde metallplaten 70 på plass mot termoplastplaten 10. Hodet 60 kan dannes med den ultra-lydoppvarmede, hodedannende matrise 50 på fig. 5. The expanded head 60 is then formed on the pointed end of the nail 52 to hold the metal sheet 70 in place against the thermoplastic sheet 10. The head 60 can be formed with the ultra-sonic heated head forming die 50 of FIG. 5.
Skjønt alle de forskjellige utførelsesformer av oppfinnelsen som er angitt ovenfor har vist og beskrevet en fast termoplastplate 10 som har et fast oppvarmet parti 20 gjennom hvilket den spissede festeanordning drives, ligger det også innenfor oppfinnelsens omfang å skaffe en forformet åpning (ikke vist) i termoplastplaten 10 som fungerer som et styrehull. Det er også påtenkt at termoplastplaten 10 kan ha partiet 20 derav varmet opp rundt det forformede styrehull før termoplastfesteanordningen drives eller på annen måte anordnes gjennom styrehullet i platen 10. Although all the various embodiments of the invention set forth above have shown and described a fixed thermoplastic sheet 10 having a fixed heated portion 20 through which the pointed fastening device is driven, it is also within the scope of the invention to provide a preformed opening (not shown) in the thermoplastic sheet 10 which acts as a guide hole. It is also intended that the thermoplastic plate 10 can have the portion 20 thereof heated around the pre-formed guide hole before the thermoplastic attachment device is operated or otherwise arranged through the guide hole in the plate 10.
Videre er der i forskjellige utførelsesformer som angitt ovenfor i alle tilfeller angitt at festeanordningen har en spiss ende som drives gjennom termoplastplatene. Det ligger imidlertid innenfor oppfinnelsens omfang å drive en ikke-spisset ende av termoplastfesteanordningen gjennom et oppvarmet parti i en termoplastplate. Det skal forstås at spisshet er et spørsmål om grad, og jo mer termoplastplaten er blitt myknet ved forvarming, desto mindre spiss behøver festeanordningen å være før den kan drives gjennom den myknede termoplastplate. Furthermore, in various embodiments as stated above, in all cases it is stated that the fastening device has a pointed end which is driven through the thermoplastic plates. However, it is within the scope of the invention to drive a non-pointed end of the thermoplastic fastening device through a heated part in a thermoplastic sheet. It should be understood that sharpness is a matter of degree, and the more the thermoplastic sheet has been softened by preheating, the less sharp the fastener needs to be before it can be driven through the softened thermoplastic sheet.
Således kan det ses at gjenstandene og fremgangsmåtene i henhold til oppfinnelsen lett oppnår de hensikter og fordeler som er nevnt såvel som de som er iboende. Thus, it can be seen that the objects and methods according to the invention easily achieve the purposes and advantages that are mentioned as well as those that are inherent.
