Abstract
A kind of advanced composite material process for roll-forming fibre reinfored glass, this invention adopts carbon fiber or ceramic fiber as the strongthener in the matrix material, adopts glass as the body material in the matrix material.Strongthener carbon fiber or ceramic fiber are cut into short silk, the body material glass fibre is worn into glass powder, then two kinds of materials are inserted add in the container that water mixes, drainage, the finish mix group of oven dry, to expect that group inserts process furnace and send into roll after softening and make tablet, tablet sent into to come out of the stove when treating that tablet reaches glass transition temperature in the process furnace again send into molding roller and be rolled or extrude, can be made into various needed finished section bars.
Description
The invention belongs to the technical field of advanced composite material production method.
At present the body material that uses of matrix material is divided into three kinds of resin base, metal matrix and ceramic bases.Wherein resin base is to use the widest matrix material in the existing industry, and this material use temperature is low, corrosion-resistant, complex forming technology and cost height; The metal-base composites moulding is then more difficult, and cost is far above polymer matrix composites; Ceramic matric composite is the matrix material that grows up for the hot operation parts that satisfy engine and spacecraft.But its forming method complexity, the scantling poor stability, so ceramic matric composite and metal-base composites all are in the developmental research stage.The forming method of above-mentioned matrix material mostly is intermittent and produces, the cost height, and the quality instability, efficient is lower.
In order to overcome above-mentioned deficiency, the objective of the invention is to design a kind of new processing method, produce a kind of novel composite material, the shortcoming of workout cost height, moulding complexity, temperature tolerance and corrosion-resistant difference, and make it to reach the purpose that serialization is produced.
Well-known glass is a kind of material of excellent property, glass use temperature height, good corrosion resistance, cost is low, material source is wide, particularly has the favorable manufacturability energy, as after being heated to softening temperature, plastic various desired shape, therefore to select glass for use be body material in the matrix material in the present invention, and selecting carbon fiber or ceramic fiber for use is strongthener, adopts the producing and manufacturing technique of rolling or extrusion moulding, create a kind of processing method of producing advanced composite material, i.e. process for roll-forming fibre reinfored glass.
Processing method of the present invention is: at first select carbon fiber or ceramic fiber to be cut into short silk as the strongthener in the matrix material, selecting then has the fiber of alkali glass or other glass as the body material in the matrix material, and the body material glass fibre worn into glass powder, then carbon fiber or ceramic fiber being added water with glass powder mixes in container, using ultrasonic generator to carry out oscillatory type simultaneously stirs, filter moisture content after the mixing and with compound oven dry or dry, dried compound becomes bulk Preblend, Preblend group inserted in the process furnace (3) by furnace charge mouth (9) be heated to above glass transition temperature, come out of the stove then and send into bloom roll (2) through feed worm (8) and be rolled into tablet, tablet sent into again carry out thermoplastic in the process furnace (3) and carry out formation rolling after feed worm (5) is sent into molding roller (6), after rolling, just make finished section bar, if the tubulation material can be by being extruded into moulding mixture mouth (4) extrusion moulding.
The step that realizes this technology is:
One, at first get the raw materials ready: preparing body material has alkali glass or other glass fiber strand, and preparing the strongthener model is carbon fiber or the ceramic fiber tow of T300, and the carbon fiber filament diameter is about 8 μ.
Two, short cutting: it is that the chopped strand of 10mm～20mm is stand-by that strongthener carbon fiber or ceramic fiber tow are cut into length with filament cutter.
Three, grind: be cooled to ambient temperature again after the body material glass fibre is heated to 700 ℃, this moment, the glass fibre embrittlement ground to form glass powder with shredder with the body material glass fibre again, and its powder granularity is 8-12 μ, and the glass powder that mill is good is stand-by.
Four, mix: with volume fraction is that 30%～70% strongthener carbon chopped fiber is put into container and added water and use ultrasonic vibration to make staple fibre Shu Zhendong loose, be that 30%～70% glass powder is inserted in the container and mixed then with volume fraction, the add-on of water is glass powder and short carbon fiber gross weight 50 times～100 times, vibrate mixing after adding well, degree of mixing evenly gets final product for range estimation is apparent.The volume ratio of two kinds of materials also can be 1: 1.
Five, drainage, oven dry: compound inserted in the filtering net water filtered, then the compound of elimination water is inserted temperature and be in 100 ℃ the baking oven and toast 10～20 minutes, or seasoning also can, dried compound becomes bulk Preblend.
Six, heating: owing in the bulk Preblend space and loose is arranged, therefore to carry out heat treated, bulk Preblend is sent in the process furnace (3) through the opening for feed (9) of process furnace (3), with furnace temperature rise to 720 ℃～800 ℃ reach temperature after, then can come out of the stove when treating that bulk Preblend temperature is higher than glass transition temperature and send into bloom roll (2) and be rolled through feed worm (8).
Seven, breaking down: when Preblend reaches glass transition temperature in process furnace (3), can come out of the stove and send into bloom roll (2) through feed worm (8) and carry out breaking down, the surface temperature of bloom roll this moment (2) should reach 550 ℃～650 ℃, if the too low meeting of temperature of bloom roll (2) causes the Preblend roll banding bad rolling.The temperature of bloom roll (2) can adopt process furnace (3) for bloom roll heats up, and also can adopt membranaceous heating mode to be heated in bloom roll (2) surface.Spacing between calender two bloom rolls (2) should be transferred to 0.1～1 millimeter, and the Preblend after the heating rolls into the thick tablet of 0.1～1 millimeter after breaking down, the closely knit tight of tablet structure, and glass powder and short carbon fiber become one.Send into discharge port and feed worm (8) control of the material amount of roll by process furnace (3), feed worm (8) and (6) are rotated by motor (1) and (2) control.
Eight, heating, formation rolling: tablet enters process furnace (3) furnace temperature again behind bloom roll (2) still be 720 ℃～850 ℃ heating once more, treat then can come out of the stove when tablet reaches glass transition temperature through feed worm (5), send molding roller (6) rolling after coming out of the stove immediately, change rolling difform section roll, then can roll out the section bar of the shape that requires, as can be rolled into profiled materials such as sheet material, angle section, channel section.Can be as the rolled tube section bar by extrusion moulding mouth (4) extruding pipe material.Finish to this whole technological process.But, therefore can carry out post forming, as get the part that can be made into arbitrary shape when a sheet material is heated to glass transition temperature because glass ware forming is good.
Advantage of the present invention is: the rolling or extruding-out process of fiber reinforcement glass, it is the method that a kind of serialization is produced, this processing method can be enhanced productivity, reduce labour intensity, cost is low, and the quality height adopts the sheet material and the profiled material of all size of the rolling or extrusion moulding of this technology, easy to use, can select suitable material as required during use.Adopt the matrix material of the rolling or extrusion moulding of the fiber reinforcement glass of this explained hereafter, its advantage is high temperature resistant, and is anticorrosive, intensity is high, flame retardant properties good, and post forming is good and cost is low, and material source is wide.This advanced composite material can be widely used in petrochemical complex, and aerospace are in the fields such as automobile making and building.
