Abstract

PROBLEM TO BE SOLVED: To prevent orientation of a reinforced fiber from being disturbed in the vicinity of a projection portion, when the projection portion is provided in a resin product containing the reinforced fiber.SOLUTION: A second linear rib 18 as a projection portion is formed using a starting material formed of a second fiber reinforced resin containing a second reinforced fiber 32 in a second matrix resin. Then, the second linear rib 18 is joined to a base portion 12 formed of a first fiber reinforced resin containing a first reinforced fiber 30 in a first matrix resin, which prevents the first reinforced fiber 30 contained in the base portion 12 from entering into the rib, and also simultaneously prevents the second reinforced fiber 32 contained in the second linear rib 18 from entering into the base portion 12.SELECTED DRAWING: Figure 2

Description

本発明は、基部と、該基部から突出した突起部とを有する樹脂製品及びその製造方法に関する。   The present invention relates to a resin product having a base and a protrusion protruding from the base, and a method for manufacturing the same.

例えば、薄肉で広面積のパネル形状構造体を、マトリックス樹脂中に強化繊維を含めた繊維強化樹脂から形成することがある。この場合、強度や剛性を確保するべく、図７に示すように、板材形状の基部１の一端面にリブやボス等の突起部２を設けて突起部付板材３とし、これをパネル形状構造体とすることが広汎に行われる。   For example, a thin-walled and wide-area panel-shaped structure may be formed from a fiber reinforced resin including a reinforced fiber in a matrix resin. In this case, in order to ensure strength and rigidity, as shown in FIG. 7, a protrusion 2 such as a rib or a boss is provided on one end surface of the base 1 in the form of a plate to form a plate 3 with a protrusion. The body is widely used.

この種の突起部付板材３（パネル形状構造体）は、従来、熱プレス成形によって作製されている。すなわち、強化繊維４を含有した繊維強化樹脂板を成形型のキャビティに配置し、該繊維強化樹脂板に熱を付与しながら成形型で押圧する。繊維強化樹脂板が熱によって軟化するため、マトリックス樹脂の一部がキャビティ内を流動し、突起部２を得るための成形部に導入される。この成形部によって突起部２が成形されるとともに、押圧によって圧潰された繊維強化樹脂板から基部１が成形される。これにより、基部１と突起部２を有する突起部付板材３が得られる。   This kind of plate material 3 with projections (panel-shaped structure) has been conventionally produced by hot press molding. That is, a fiber reinforced resin plate containing the reinforced fibers 4 is placed in a cavity of a mold and pressed with the mold while heat is applied to the fiber reinforced resin plate. Since the fiber-reinforced resin plate is softened by heat, a part of the matrix resin flows in the cavity and is introduced into the molding portion for obtaining the protrusion 2. The projecting portion 2 is molded by this molded portion, and the base portion 1 is molded from a fiber-reinforced resin plate that is crushed by pressing. Thereby, the board | plate material 3 with a protrusion part which has the base 1 and the protrusion part 2 is obtained.

ここで、繊維強化樹脂板のマトリックス樹脂が押圧されて成形部に流動するときには、該マトリックス樹脂に含まれる強化繊維４も流動する。従って、強化繊維４は、基部１中の突起部２の近傍において、基部１から突起部２に向かうように配向する。換言すれば、強化繊維４の中には、長さ方向の途中で湾曲するものや、基部１と突起部２の双方に跨るものが存在する。   Here, when the matrix resin of the fiber reinforced resin plate is pressed and flows into the molding part, the reinforcing fibers 4 contained in the matrix resin also flow. Accordingly, the reinforcing fibers 4 are oriented in the vicinity of the protrusion 2 in the base 1 so as to go from the base 1 toward the protrusion 2. In other words, some of the reinforcing fibers 4 are curved in the middle of the length direction, and others are straddling both the base portion 1 and the protruding portion 2.

すなわち、この場合、基部１と突起部２の境界で強化繊維４の配向が乱れる。この乱れに起因し、基部１の特に引っ張り強度が低下してしまう。また、引け巣が形成され易くなるので、美観が損なわれる。   That is, in this case, the orientation of the reinforcing fibers 4 is disturbed at the boundary between the base portion 1 and the protruding portion 2. Due to this disturbance, particularly the tensile strength of the base 1 is lowered. In addition, since the shrinkage nest is easily formed, the aesthetic appearance is impaired.

以上のような不都合を回避するべく、特許文献１には、溶融した中間材を介して基部１と突起部２を接合することが提案されている。この技術では、基部１から突起部２にマトリックス樹脂や強化繊維４が流動することはない。従って、強化繊維４の配向が乱れることを抑制し得ると考えられる。   In order to avoid the inconveniences as described above, Patent Document 1 proposes joining the base 1 and the protrusion 2 via a melted intermediate material. In this technique, the matrix resin and the reinforcing fibers 4 do not flow from the base 1 to the protrusion 2. Therefore, it is considered that the orientation of the reinforcing fibers 4 can be prevented from being disturbed.

特許第５５００１７７号公報Japanese Patent No. 5500197

しかしながら、中間材を用いる場合、取り扱う部材の個数が増加するために成形過程が複雑となる。また、突起部付板材の基部と中間部を接合するので、合計厚みや重量が大きくなる。従って、肉厚を小さくすべき製品として得ることや軽量化を図ることが困難である。   However, when an intermediate material is used, the number of members to be handled increases, and the molding process becomes complicated. Moreover, since the base part and intermediate part of a board | plate material with a projection part are joined, total thickness and weight become large. Therefore, it is difficult to obtain a product whose thickness should be reduced and to reduce the weight.

本発明は上記した問題を解決するためになされたもので、突起部の近傍において強化繊維の配向が乱れることが抑制され、しかも、肉厚を小さくすることや軽量化を図ることが可能な樹脂製品及びその製造方法を提供することを目的とする。   The present invention has been made to solve the above-described problem, and is capable of suppressing the disturbance of the orientation of the reinforcing fibers in the vicinity of the protruding portion, and further reducing the thickness and reducing the weight. It aims at providing a product and its manufacturing method.

前記の目的を達成するために、本発明は、第１マトリックス樹脂内に第１強化繊維を含有した第１繊維強化樹脂からなる基部と、第２マトリックス樹脂内に第２強化繊維を含有した第２繊維強化樹脂からなり、前記基部から突出するように設けられた突起部とを有する樹脂製品であって、
前記基部に含まれる前記第１強化繊維が前記突起部に進入するのを抑制し、
且つ前記突起部に含まれる前記第２強化繊維が前記基部に進入するのを抑制したことを特徴とする。 In order to achieve the above object, the present invention provides a base portion made of a first fiber reinforced resin containing a first reinforcing fiber in a first matrix resin and a second reinforcing fiber containing a second reinforcing fiber in the second matrix resin. A resin product comprising a two-fiber reinforced resin and having a protrusion provided so as to protrude from the base,
Suppressing the first reinforcing fiber contained in the base from entering the protrusion,
In addition, the second reinforcing fiber included in the protrusion is prevented from entering the base.

すなわち、本発明においては、突起部の近傍で強化繊維の配向が乱れることが防止されている。このため、突起部の近傍で引っ張り強度等の諸特性が低下することが回避される。加えて、引け巣が形成され難くなるので、美観を保つこともできる。   That is, in the present invention, the orientation of the reinforcing fibers is prevented from being disturbed in the vicinity of the protrusions. For this reason, it is avoided that various characteristics, such as tensile strength, fall in the vicinity of a projection part. In addition, since it becomes difficult to form shrinkage nests, it is possible to keep the beauty.

さらに、基部と突起部の間に中間材を介在させる必要は特にない。このため、樹脂製品の肉厚を小さくすることや、軽量化を図ることが可能である。   Furthermore, it is not particularly necessary to interpose an intermediate material between the base and the protrusion. For this reason, it is possible to reduce the thickness of the resin product and to reduce the weight.

また、本発明は、第１マトリックス樹脂内に第１強化繊維を含有した第１繊維強化樹脂からなる基部と、第２マトリックス樹脂内に第２強化繊維を含有した第２繊維強化樹脂からなり、前記基部から突出するように設けられた突起部とを有する樹脂製品の製造方法であって、
前記第２強化繊維を含む第２繊維強化樹脂を軟化させて押圧し、その後に硬化させることで前記突起部を成形する工程と、
成形型内に前記突起部及び前記基部を収容し、前記第１マトリックス樹脂又は前記第２マトリックス樹脂の双方の融点以上に加熱しながら押圧して、前記突起部を前記基部に接合する工程と、
を有することを特徴とする。 Further, the present invention comprises a base made of a first fiber reinforced resin containing a first reinforcing fiber in the first matrix resin, and a second fiber reinforced resin containing a second reinforcing fiber in the second matrix resin, A method of manufacturing a resin product having a protrusion provided so as to protrude from the base,
Softening and pressing the second fiber reinforced resin containing the second reinforcing fibers, and then forming the protrusions by curing; and
Housing the protrusion and the base in a mold, pressing while heating above the melting point of both the first matrix resin or the second matrix resin, and bonding the protrusion to the base;
It is characterized by having.

すなわち、本発明においては、基部と突起部を個別に作製した後、これらを接合するようにしている。このため、基部（第１繊維強化樹脂）中の第１強化繊維が突起部に進入することが防止される。同時に、突起部（第２繊維強化樹脂）中の第２強化繊維が基部に進入することも防止される。以上のような理由から、突起部の近傍で強化繊維の配向が乱れることが回避される。   In other words, in the present invention, the base portion and the protrusion portion are individually manufactured and then joined together. For this reason, it is prevented that the 1st reinforcement fiber in a base (1st fiber reinforced resin) penetrates into a projection part. At the same time, the second reinforcing fiber in the protrusion (second fiber reinforced resin) is also prevented from entering the base. For the above reasons, it is avoided that the orientation of the reinforcing fibers is disturbed in the vicinity of the protrusions.

従って、突起部の近傍で引っ張り強度等の諸特性が低下することが回避されるとともに、引け巣が形成されることが抑制されて美観に優れる樹脂製品を容易に得ることができる。   Accordingly, it is possible to avoid a decrease in various properties such as tensile strength in the vicinity of the protrusion, and it is possible to easily obtain a resin product excellent in aesthetics by suppressing the formation of a shrinkage nest.

なお、突起部は成形型で成形すればよいが、当該成形型は、突起部と基部を接合するときに用いる成形型と同一のものであってもよいし、別個のものであってもよい。   The protrusion may be formed with a mold, but the mold may be the same as the mold used when the protrusion and the base are joined, or may be separate. .

樹脂製品は、突起部に連なり且つ該突起部と同一の第２繊維強化樹脂からなるとともに、該突起部に比して幅広且つ薄肉の介在部を有するものであってもよい。この場合においては、介在部は、基部と突起部の間に介在する。そして、介在部に含まれる第２強化繊維は、基部に進入することが抑制されている。勿論、基部に含まれる第１強化繊維は、介在部に進入することが抑制されている。   The resin product may be formed of a second fiber reinforced resin that is continuous with the protruding portion and is the same as the protruding portion, and has a wider and thinner intervening portion than the protruding portion. In this case, the interposition part is interposed between the base part and the protrusion part. And it is suppressed that the 2nd reinforcing fiber contained in an interposition part enters a base. Of course, the first reinforcing fibers included in the base are prevented from entering the interposition.

この構成は、特に、突起部を複数個作製するときに有効である。すなわち、複数個の突起部同士を連結させた方が、取り扱いが容易になるからである。   This configuration is particularly effective when a plurality of protrusions are produced. That is, it is because the handling becomes easier when the plurality of protrusions are connected to each other.

本発明によれば、突起部の近傍で強化繊維の配向が乱れることを防止するようにしているので、突起部の近傍で引っ張り強度等の諸特性が低下することが回避される。しかも、引け巣が形成され難くなる。その結果として、諸特性及び美観に優れた樹脂製品が得られる。   According to the present invention, since the orientation of the reinforcing fiber is prevented from being disturbed in the vicinity of the protrusion, it is possible to avoid various characteristics such as tensile strength from being deteriorated in the vicinity of the protrusion. Moreover, shrinkage nests are difficult to form. As a result, a resin product excellent in various properties and aesthetics can be obtained.

また、基部と突起部の間に中間材を介在させる必要が特にないので、樹脂製品の肉厚を小さくすることや軽量化を図ることが可能となる。   In addition, since it is not particularly necessary to interpose an intermediate material between the base and the protrusion, the thickness of the resin product can be reduced and the weight can be reduced.

以下、本発明に係る樹脂製品及びその製造方法につき好適な実施の形態を挙げ、添付の図面を参照して詳細に説明する。なお、この実施の形態では、樹脂製品としてパネル形状構造体を例示する。   Hereinafter, preferred embodiments of the resin product and the manufacturing method thereof according to the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, a panel-shaped structure is illustrated as a resin product.

図１は、本実施の形態に係るパネル形状構造体１０（樹脂製品）の概略全体斜視図である。このパネル形状構造体１０は、基部１２と、突起部としての湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０とを有する。さらに、図２に詳細を示すように、湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０は、介在部２２を介して互いに連なっている。   FIG. 1 is a schematic overall perspective view of a panel-shaped structure 10 (resin product) according to the present embodiment. The panel-shaped structure 10 includes a base 12, a curved rib 14 as a protrusion, a first linear rib 16, a second linear rib 18, and a third linear rib 20. Further, as shown in detail in FIG. 2, the curved rib 14, the first linear rib 16, the second linear rib 18, and the third linear rib 20 are connected to each other via the interposition part 22.

基部１２は、平板部２４の一端部近傍が約９０°折曲されることで立ち上がり部２６が形成され、さらに、該立ち上がり部２６が約９０°折曲されることで短尺縁部２８が形成された形状となっている。平板部２４の図１における下端面が、ユーザーが視認する意匠面となる。一方、平板部２４の図１における上端面は、前記介在部２２に覆われる。すなわち、介在部２２は平板部２４に溶着（接合）している。湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０は、介在部２２の上端面から突出するように設けられている。   The base portion 12 is formed with a rising portion 26 when the vicinity of one end of the flat plate portion 24 is bent by about 90 °, and further, the short edge portion 28 is formed by bending the rising portion 26 with about 90 °. It has become a shape. The lower end surface in FIG. 1 of the flat plate portion 24 is a design surface visually recognized by the user. On the other hand, the upper end surface of the flat plate portion 24 in FIG. 1 is covered with the interposition portion 22. That is, the interposition part 22 is welded (joined) to the flat plate part 24. The curved rib 14, the first linear rib 16, the second linear rib 18, and the third linear rib 20 are provided so as to protrude from the upper end surface of the interposition part 22.

略半円環形状をなす湾曲状リブ１４は、図１における下端面が平板部２４の上端面に連接する。また、内周壁側から外周壁側に向かう方向に切り欠かれることで形成される２個の厚み方向側面が、立ち上がり部２６に連接する。すなわち、湾曲状リブ１４は、立ち上がり部２６に溶着（接合）している。   The curved rib 14 having a substantially semicircular ring shape has the lower end surface in FIG. 1 connected to the upper end surface of the flat plate portion 24. Further, two thickness direction side surfaces formed by cutting out in the direction from the inner peripheral wall side to the outer peripheral wall side are connected to the rising portion 26. That is, the curved rib 14 is welded (joined) to the rising portion 26.

さらに、湾曲状リブ１４の外周壁の同一箇所から、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０が放射状に突出する。これら第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０の下端面が、介在部２２の上端面に連接する。   Further, the first linear rib 16, the second linear rib 18, and the third linear rib 20 protrude radially from the same location on the outer peripheral wall of the curved rib 14. The lower end surfaces of the first linear rib 16, the second linear rib 18, and the third linear rib 20 are connected to the upper end surface of the interposition part 22.

介在部２２は、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０に比して幅広且つ肉薄である。介在部２２の厚みＴ（図２参照）は、典型的には１ｍｍ以下に設定される。金型（後述の下型４２、上型４４）を保護する観点から、厚みＴを０．２ｍｍ程度とすることが好ましい。   The interposition part 22 is wider and thinner than the first linear rib 16, the second linear rib 18, and the third linear rib 20. The thickness T (see FIG. 2) of the interposition part 22 is typically set to 1 mm or less. From the viewpoint of protecting the mold (the lower mold 42 and the upper mold 44 described later), the thickness T is preferably about 0.2 mm.

以上の構成において、前記基部１２（平板部２４、立ち上がり部２６及び短尺縁部２８）は、第１マトリックス樹脂内に、図２に示す第１強化繊維３０を含有した第１繊維強化樹脂からなる。第１マトリックス樹脂としては、例えば、ε−カプロラクタム（ナイロン）樹脂やエポキシ樹脂等が挙げられる。また、第１強化繊維３０の好適な例としては炭素繊維やガラス繊維が挙げられる。特に、長さが５ｍｍ〜十数ｍｍである長繊維や連続繊維であるとよい。   In the above configuration, the base portion 12 (the flat plate portion 24, the rising portion 26, and the short edge portion 28) is made of the first fiber reinforced resin containing the first reinforced fibers 30 shown in FIG. 2 in the first matrix resin. . Examples of the first matrix resin include ε-caprolactam (nylon) resin and epoxy resin. Moreover, as a suitable example of the 1st reinforcement fiber 30, carbon fiber and glass fiber are mentioned. In particular, it may be a long fiber or a continuous fiber having a length of 5 mm to several tens of mm.

第１強化繊維３０は、基部１２の長手方向に指向して延在するように配向していてもよいし、指向方向がランダムであってもよい。又は、クロス材であってもよい。   The first reinforcing fibers 30 may be oriented so as to extend in the longitudinal direction of the base 12, or the directing direction may be random. Or a cloth material may be sufficient.

一方、湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８、第３直線状リブ２０及びこれらを連結する介在部２２は、第２マトリックス樹脂内に第２強化繊維３２を含有した第２繊維強化樹脂からなる。第２マトリックス樹脂は、第１マトリックス樹脂と同一の樹脂であってもよいし、異種の樹脂であってもよい。   On the other hand, the curved ribs 14, the first linear ribs 16, the second linear ribs 18, the third linear ribs 20, and the intervening portions 22 connecting them contain the second reinforcing fibers 32 in the second matrix resin. Made of the second fiber reinforced resin. The second matrix resin may be the same resin as the first matrix resin, or may be a different resin.

また、第２強化繊維３２も、第１強化繊維３０と同一の繊維であってもよいし、異種の繊維であってもよい。ただし、第２強化繊維３２は、長さが１ｍｍに満たない短繊維であることが好ましい。第２強化繊維３２は、各リブ１４、１６、１８、２０の長手方向に指向して延在するように配向していてもよいし、指向方向がランダムであってもよい。   Further, the second reinforcing fiber 32 may be the same fiber as the first reinforcing fiber 30 or may be a different type of fiber. However, the second reinforcing fiber 32 is preferably a short fiber having a length of less than 1 mm. The second reinforcing fibers 32 may be oriented so as to extend in the longitudinal direction of the ribs 14, 16, 18, 20, or the directing direction may be random.

平板部２４、介在部２２及び第２直線状リブ１８の接合箇所の近傍を、図２に拡大して模式的に示す。この図２に示すように、第１強化繊維３０は平板部２４に主に存在し、介在部２２及び第２直線状リブ１８に進入することが抑制されている。同様に、第２強化繊維３２は介在部２２及び第２直線状リブ１８に主に存在し、平板部２４に進入することが抑制されている。なお、残余の湾曲状リブ１４、第１直線状リブ１６、第３直線状リブ２０についても上記と同様である。   FIG. 2 schematically shows the vicinity of the joining portion of the flat plate portion 24, the interposition portion 22, and the second linear rib 18. As shown in FIG. 2, the first reinforcing fibers 30 are mainly present in the flat plate portion 24, and are prevented from entering the intervening portion 22 and the second linear rib 18. Similarly, the second reinforcing fiber 32 is mainly present in the interposition part 22 and the second linear rib 18 and is prevented from entering the flat plate part 24. The remaining curved ribs 14, the first linear ribs 16, and the third linear ribs 20 are the same as described above.

要するに、第１強化繊維３０と第２強化繊維３２は別部位に個別に存在しており、同一部位に混在し難い。すなわち、第１強化繊維３０及び第２強化繊維３２が基部１２と介在部２２（ないし各リブ１４、１６、１８、２０）に跨る可能性は低い。しかも、第１強化繊維３０が各リブ１４、１６、１８、２０に指向して湾曲したり、第２強化繊維３２が基部１２の長手方向に沿って湾曲したりすることが抑制される。   In short, the 1st reinforcement fiber 30 and the 2nd reinforcement fiber 32 exist separately in another site | part, and it is hard to be mixed in the same site | part. That is, the possibility that the first reinforcing fiber 30 and the second reinforcing fiber 32 straddle the base portion 12 and the interposition portion 22 (or the ribs 14, 16, 18, 20) is low. In addition, the first reinforcing fiber 30 is prevented from being bent toward the ribs 14, 16, 18, and 20, and the second reinforcing fiber 32 is suppressed from being bent along the longitudinal direction of the base portion 12.

第１強化繊維３０が平板部２４にのみ存在し、介在部２２及び各リブ１４、１６、１８、２０に進入しておらず、且つ第２強化繊維３２が介在部２２及び各リブ１４、１６、１８、２０にのみ存在し、平板部２４に進入していないことが最も好ましい。   The first reinforcing fiber 30 exists only in the flat plate portion 24, does not enter the interposition portion 22 and the ribs 14, 16, 18, and 20, and the second reinforcing fiber 32 exists in the interposition portion 22 and the ribs 14 and 16. , 18 and 20, and most preferably not entering the flat plate portion 24.

このように、本実施の形態に係るパネル形状構造体１０では、基部１２と各リブ１４、１６、１８、２０の境界で第１強化繊維３０及び第２強化繊維３２の配向が乱れることが防止されている。従って、引っ張り強度等の諸特性が低下することが回避される。加えて、引け巣が形成されることも回避されるので、美観が保たれるという利点もある。   As described above, in the panel-shaped structure 10 according to the present embodiment, the orientation of the first reinforcing fiber 30 and the second reinforcing fiber 32 is prevented from being disturbed at the boundary between the base 12 and the ribs 14, 16, 18, 20. Has been. Therefore, it is avoided that various properties such as tensile strength are deteriorated. In addition, since the formation of shrinkage nests is avoided, there is also an advantage that aesthetics are maintained.

次に、本実施の形態に係る樹脂製品の製造方法につき、上記したパネル形状構造体１０の製造過程との関係で説明する。   Next, the manufacturing method of the resin product according to the present embodiment will be described in relation to the manufacturing process of the panel-shaped structure 10 described above.

パネル形状構造体１０は、例えば、図３に要部概略断面が示される熱プレス成形装置４０によって得ることができる。この熱プレス成形装置４０につき概略説明すると、該熱プレス成形装置４０は、位置決め固定された下型４２（成形型）と、昇降動作によって該下型４２に対して接近又は離間する上型４４（成形型）とを有する。   The panel-shaped structure 10 can be obtained, for example, by a hot press molding apparatus 40 whose main part schematic cross section is shown in FIG. The hot press molding apparatus 40 will be described briefly. The hot press molding apparatus 40 includes a lower mold 42 (molding mold) that is positioned and fixed, and an upper mold 44 (approaching or separating from the lower mold 42 by a lifting operation). Mold).

下型４２には、湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０の各々を成形するためのリブ成形部が形成される。ただし、図３においては、視線の関係上、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０を成形する直線状リブ成形部４６のみを示している。下型４２には、さらに、直線状リブ成形部４６よりも一層陥没した凹部４８が形成されるとともに、図示しないノックアウトピンが設けられる。   The lower mold 42 is formed with rib forming portions for forming each of the curved rib 14, the first linear rib 16, the second linear rib 18, and the third linear rib 20. However, in FIG. 3, only the linear rib forming part 46 for forming the first linear rib 16, the second linear rib 18, and the third linear rib 20 is shown because of the line of sight. The lower mold 42 is further provided with a recess 48 that is further depressed than the linear rib molding portion 46 and a knockout pin (not shown).

一方の上型４４には、下型４２の前記凹部４８に進入する凸部５０が突出形成される。この上型４４は、図示しない昇降機構の作用下に昇降動作することが可能である。上型４４が下降して下型４２に接近することに伴い、型閉じがなされてキャビティが形成される。これとは逆に、上型４４が上昇して下型４２から離間することにより、型開きがなされる。   On the other hand, the upper mold 44 is formed with a protruding portion 50 protruding into the recessed portion 48 of the lower mold 42. The upper mold 44 can be moved up and down under the action of a lifting mechanism (not shown). As the upper die 44 descends and approaches the lower die 42, the die is closed and a cavity is formed. On the contrary, when the upper mold 44 rises and is separated from the lower mold 42, the mold is opened.

下型４２及び上型４４には、キャビティ形成面の近傍に温調用流路５２、５４がそれぞれ形成される。これら温調用流路５２、５４には、温調用オイルが流通される。   In the lower mold 42 and the upper mold 44, temperature control channels 52 and 54 are formed in the vicinity of the cavity forming surface, respectively. Temperature control oil is circulated through these temperature control channels 52 and 54.

パネル形状構造体１０を得るには、先ず、第２繊維強化樹脂からなる出発材５６を下型４２の所定位置に配置するとともに、温調用流路５２、５４に温オイルを流通させる。温オイルの温度は、出発材５６の第２マトリックス樹脂が下型４２及び上型４４から熱を受けて軟化し得るように設定する。   In order to obtain the panel-shaped structure 10, first, the starting material 56 made of the second fiber reinforced resin is disposed at a predetermined position of the lower mold 42, and warm oil is circulated through the temperature adjustment channels 52 and 54. The temperature of the hot oil is set so that the second matrix resin of the starting material 56 can be softened by receiving heat from the lower mold 42 and the upper mold 44.

温オイルが流通することにより、下型４２及び上型４４の温度が上昇する。下型４２及び上型４４の温度が所定の温度まで上昇した後、前記昇降機構の作用下に上型４４を下降させて型閉じを行い、図３に示すように、下型４２と上型４４で出発材５６を挟持した状態とする。この時点で、下型４２と上型４４の温度が第２マトリックス樹脂の融点以上、例えば、６−ナイロン樹脂の場合は約２２０℃以上となっていることが好ましい。   As the warm oil flows, the temperatures of the lower mold 42 and the upper mold 44 rise. After the temperature of the lower mold 42 and the upper mold 44 rises to a predetermined temperature, the upper mold 44 is lowered under the action of the elevating mechanism to close the mold, and as shown in FIG. 44, the starting material 56 is sandwiched. At this time, it is preferable that the temperature of the lower mold 42 and the upper mold 44 is equal to or higher than the melting point of the second matrix resin, for example, about 220 ° C. in the case of 6-nylon resin.

この後にさらに上型４４を下降させると、出発材５６に荷重が付与される。この荷重付与前に下型４２と上型４４の温度が第２マトリックス樹脂の融点以上となっている場合、荷重付与に追従して出発材５６が迅速に圧潰される。出発材５６が下型４２及び上型４４によって既に十分に加熱されているので、軟化可能となっているからである。   When the upper die 44 is further lowered thereafter, a load is applied to the starting material 56. If the temperature of the lower mold 42 and the upper mold 44 is equal to or higher than the melting point of the second matrix resin before the load is applied, the starting material 56 is quickly crushed following the load application. This is because the starting material 56 has already been sufficiently heated by the lower mold 42 and the upper mold 44 and can be softened.

出発材５６が圧潰されると、図４に示すように、該出発材５６がキャビティに沿って展延する。展延した出発材５６（第２マトリックス樹脂及び第２強化繊維３２）は、直線状リブ成形部４６をはじめとするリブ成形部に流入する。これにより、湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０が成形される。なお、図示の例では、出発材５６は凹部４８に到達していないが、凹部４８まで展延させるようにしてもよい。   When the starting material 56 is crushed, as shown in FIG. 4, the starting material 56 extends along the cavity. The spread starting material 56 (second matrix resin and second reinforcing fibers 32) flows into the rib forming section including the linear rib forming section 46. Thereby, the curved rib 14, the 1st linear rib 16, the 2nd linear rib 18, and the 3rd linear rib 20 are shape | molded. In the illustrated example, the starting material 56 does not reach the recess 48, but may be extended to the recess 48.

また、リブ成形部に流入されなかった残余の出発材５６は、キャビティ中、下型４２と上型４４の間のクリアランスに残留する。この残留した出発材５６により、介在部２２が成形される。すなわち、湾曲状リブ１４、第１直線状リブ１６、第２直線状リブ１８及び第３直線状リブ２０と、これらのリブ１４、１６、１８、２０と一体的に連なる介在部２２を有する中間成形品５８が得られる。この時点で、介在部２２の厚みは、金型保護のために設定した略０．２ｍｍとなる。   The remaining starting material 56 that has not flowed into the rib forming portion remains in the clearance between the lower die 42 and the upper die 44 in the cavity. The intervening portion 22 is formed by the remaining starting material 56. That is, an intermediate portion having the curved rib 14, the first linear rib 16, the second linear rib 18, and the third linear rib 20, and the interposition portion 22 that is integrally connected to the ribs 14, 16, 18, and 20. A molded product 58 is obtained. At this time, the thickness of the interposition part 22 becomes approximately 0.2 mm set for the mold protection.

展延が完了する前、又は完了した後に、温調用流路５２、５４に流通する温調用オイルを冷オイルに切り換える。冷オイルの温度は、例えば、３０℃程度とすればよい。これにより下型４２及び上型４４の温度が低下するので、中間成形品５８の熱が下型４２及び上型４４に奪取されるようになる。その結果として、中間成形品５８の温度も低下する。中間成形品５８の温度が第２マトリックス樹脂の融点を下回ると、中間成形品５８が硬化する。   Before or after the spreading is completed, the temperature adjusting oil flowing in the temperature adjusting flow paths 52 and 54 is switched to the cold oil. The temperature of the cold oil may be about 30 ° C., for example. As a result, the temperatures of the lower mold 42 and the upper mold 44 are lowered, so that the heat of the intermediate molded product 58 is taken by the lower mold 42 and the upper mold 44. As a result, the temperature of the intermediate molded product 58 also decreases. When the temperature of the intermediate molded product 58 is lower than the melting point of the second matrix resin, the intermediate molded product 58 is cured.

次に、前記昇降機構の作用下に上型４４を上昇させ、図５に示すように型開きを行う。さらに、第１繊維強化樹脂からなる基部１２を、中間成形品５８の介在部２２上に載置する。これに先んじ、温調用流路５２、５４に流通する温調用オイルを温オイルに切り換えておく。なお、基部１２を介在部２２上に載置した後に、温調用オイルを温オイルに切り換えるようにしてもよい。また、基部１２を外部熱源によって予備加熱しておくことも可能である。   Next, the upper mold 44 is raised under the action of the lifting mechanism, and the mold is opened as shown in FIG. Further, the base 12 made of the first fiber reinforced resin is placed on the interposition part 22 of the intermediate molded product 58. Prior to this, the temperature adjusting oil flowing in the temperature adjusting flow paths 52 and 54 is switched to the temperature oil. In addition, after mounting the base part 12 on the interposition part 22, you may make it switch oil for temperature control to warm oil. It is also possible to preheat the base 12 with an external heat source.

温オイルが再流通することにより、下型４２及び上型４４の温度が再上昇する。下型４２及び上型４４の温度が所定の温度まで上昇した後、前記昇降機構の作用下に上型４４を下降させて型閉じを行い、図６に示すように、下型４２と上型４４で中間成形品５８及び基部１２を挟持した状態とする。この時点で、下型４２と上型４４の温度が第１マトリックス樹脂及び第２マトリックス樹脂の双方の融点以上となっていることが好ましい。   As the hot oil recirculates, the temperatures of the lower mold 42 and the upper mold 44 rise again. After the temperature of the lower mold 42 and the upper mold 44 rises to a predetermined temperature, the upper mold 44 is lowered under the action of the elevating mechanism to close the mold, and as shown in FIG. 44, the intermediate molded product 58 and the base 12 are sandwiched. At this time, it is preferable that the temperature of the lower mold 42 and the upper mold 44 is equal to or higher than the melting points of both the first matrix resin and the second matrix resin.

上型４４を下降させることにより、中間成形品５８に対して基部１２が押し付けられる。また、基部１２がキャビティの形状に対応する形状に変形することにより、立ち上がり部２６及び短尺縁部２８が成形される。下型４２と上型４４の温度が第１マトリックス樹脂及び第２マトリックス樹脂の融点以上となっている場合、中間成形品５８と基部１２が速やかに軟化し、互いに溶着する。すなわち、介在部２２が基部１２に溶着するとともに、湾曲状リブ１４の厚み方向側面が立ち上がり部２６に溶着する。さらに、基部１２の一部が上型４４の凸部５０に押圧され、下型４２の凹部４８に進入する。その結果、基部１２、介在部２２及び各リブ１４、１６、１８、２０を有するパネル形状構造体１０が成形されるに至る。   The base 12 is pressed against the intermediate molded product 58 by lowering the upper mold 44. Further, when the base portion 12 is deformed into a shape corresponding to the shape of the cavity, the rising portion 26 and the short edge portion 28 are formed. When the temperature of the lower mold 42 and the upper mold 44 is equal to or higher than the melting points of the first matrix resin and the second matrix resin, the intermediate molded product 58 and the base 12 are quickly softened and welded together. That is, the interposition part 22 is welded to the base part 12, and the side surface in the thickness direction of the curved rib 14 is welded to the rising part 26. Further, a part of the base portion 12 is pressed by the convex portion 50 of the upper die 44 and enters the concave portion 48 of the lower die 42. As a result, the panel-shaped structure 10 having the base 12, the interposition part 22, and the ribs 14, 16, 18, 20 is formed.

タクトタイムを可及的に短縮するときには、溶着の開始と同時、又は直後に、温調用流路５２、５４に流通する温調用オイルを冷オイルに切り換える。このため、下型４２及び上型４４の温度が速やかに低下するとともに、パネル形状構造体１０の熱が下型４２及び上型４４に奪取される。従って、パネル形状構造体１０が効率よく硬化する。   When the tact time is shortened as much as possible, the temperature adjusting oil flowing in the temperature adjusting channels 52 and 54 is switched to the cold oil simultaneously with or immediately after the start of welding. For this reason, the temperature of the lower mold 42 and the upper mold 44 quickly decreases, and the heat of the panel-shaped structure 10 is taken by the lower mold 42 and the upper mold 44. Therefore, the panel-shaped structure 10 is cured efficiently.

さらに、前記昇降機構の作用下に上型４４を上昇させて型開きを行った後、前記ノックアウトピンを作動させる。パネル形状構造体１０は、このノックアウトピンから押圧を受けることで下型４２から離型する。   Further, the upper die 44 is raised under the action of the lifting mechanism to open the die, and then the knockout pin is operated. The panel-shaped structure 10 is released from the lower mold 42 by receiving pressure from the knockout pin.

以上のように、この製造方法では、各リブ１４、１６、１８、２０及び介在部２２を先ず成形して中間成形品５８を得た後、該中間成形品５８を基部１２に溶着するようにしている。このため、中間成形品５８に含まれる第２強化繊維３２が基部１２に進入することや、基部１２に含まれる第１強化繊維３０が介在部２２ないし各リブ１４、１６、１８、２０に進入することが回避される。換言すれば、基部１２と各リブ１４、１６、１８、２０の境界で第１強化繊維３０及び第２強化繊維３２の配向が乱れることが防止される。これにより、引っ張り強度等の諸特性が低下することが回避される。また、引け巣が形成され難くなる。   As described above, in this manufacturing method, the ribs 14, 16, 18, 20 and the interposition part 22 are first molded to obtain the intermediate molded product 58, and then the intermediate molded product 58 is welded to the base 12. ing. For this reason, the second reinforcing fibers 32 included in the intermediate molded product 58 enter the base portion 12, or the first reinforcing fibers 30 included in the base portion 12 enter the interposition portion 22 or the ribs 14, 16, 18, 20. Is avoided. In other words, the orientation of the first reinforcing fiber 30 and the second reinforcing fiber 32 is prevented from being disturbed at the boundary between the base 12 and the ribs 14, 16, 18, 20. Thereby, it is avoided that various characteristics, such as tensile strength, fall. Moreover, it becomes difficult to form a shrinkage nest.

しかも、基部１２と突起部の間に中間部を介在させる必要がないので、パネル形状構造体１０の肉厚を小さくすることや、軽量化を図ることができる。   In addition, since there is no need to interpose an intermediate portion between the base portion 12 and the protruding portion, the thickness of the panel-shaped structure 10 can be reduced and the weight can be reduced.

本発明は、上記した実施の形態に特に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。   The present invention is not particularly limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

例えば、樹脂製品は、図１に示されるパネル形状構造体１０に特に限定されるものではなく、リブやボス等の突起部が存在するものであればよい。   For example, the resin product is not particularly limited to the panel-shaped structure 10 shown in FIG. 1, and any resin product having protrusions such as ribs and bosses may be used.

また、介在部２２を設ける必要は特にない。すなわち、例えば、複数個の出発材５６から第１直線状リブ１６、第２直線状リブ１８、第３直線状リブ２０と、これらに連なる湾曲状リブ１４とを成形し、各リブ１４、１６、１８、２０を基部１２に溶着するようにしてもよい。   There is no particular need to provide the interposition part 22. That is, for example, the first linear rib 16, the second linear rib 18, the third linear rib 20, and the curved rib 14 connected to these are formed from a plurality of starting materials 56, and the ribs 14, 16 are formed. 18 and 20 may be welded to the base 12.

さらに、上記の実施の形態では、１台の熱プレス成形装置４０にて中間成形品５８及びパネル形状構造体１０の双方を得るようにしているが、中間成形品５８を得るための熱プレス成形装置と、樹脂製品を得るための熱プレス成形装置とを別個のものにするようにしてもよいことは勿論である。   Further, in the above embodiment, both the intermediate molded product 58 and the panel-shaped structure 10 are obtained by one hot press molding apparatus 40. However, the hot press molding for obtaining the intermediate molded product 58 is performed. Of course, the apparatus and the hot press molding apparatus for obtaining the resin product may be made separate.

さらにまた、下型４２及び上型４４の温度調節（昇温及び降温）は、オイル媒体によるものに特に限定されるものではない。そして、下型４２と上型４４を個別に温度調節するようにしてもよいし、下型４２又は上型４４の温度調整を部分的に行うようにしてもよい。   Furthermore, the temperature adjustment (temperature increase and temperature decrease) of the lower mold 42 and the upper mold 44 is not particularly limited to that using an oil medium. The temperature of the lower mold 42 and the upper mold 44 may be adjusted individually, or the temperature of the lower mold 42 or the upper mold 44 may be partially adjusted.
