(Technology of 1) solution macerateChoose appropriate dissolvent deliquescent colophony matrix, preparation becomes solution, use carbon fiber of macerate of this kind of solution next bundle, make through stoving solvent volatilizes, final squeezing ramming is made beforehand dip makings. Nevertheless this kind of method has certain limitation, not all thermoplastic matrix can dissolve at organic dissolvent.

(Technology of macerate of 2) in suspensionMake colophony powder into suspension fluid first, fiber silk bundle immerse to be mixed in suspension fluid colophony is sufficient macerate, pass oven drying next and make colophony attributes melt position, suppress of roller of reentrance hot pressing and refrigeration can be made beforehand dip belt. (Technology of 3) pulverous maceratecarbon fiber silk bundle the electrostatic fluid-bed of the tiny powder that spreading exhibited thin; to be full of 10μm through next, make colophony powder besmears Fu is in equably fiber surface, heat through oven and hot pressing roller is pressed delay make colophony infiltrates adequately fiber, get thereby thermoplastic sheet. (4) melt dipping processSuccessive carbon fiber is put after gauze is worn, make through adjustment of round screw die its suffer force to enter the system that divide silk equably, in this system, after through spreading out roller spreads out adequately with warm-up hind, carbon fiber enters macerate system in, below high temperature high pressure, of melt thermoplastic colophony infiltration infiltrates carbon fiber, wait for after finalizing the design again drawing closes roll get successive carbon fiber increases thermoplastic beforehand dip belt. Among them technology (1) ? (Because 3) produced the reason such as efficiency of cost of craft, production, production to restrict its to produce medium wide application in industry. Melt dipping process is the macerate mould that fasciculus adopts a design, be pulled from inside the colophony below melt condition below particular tensional function and by macerate. This method shapes craft is simple, without environmental pollution, have industrialized perspective most.

Thermoplastic of carbon fiber composite material shape craft introduction

High-powered thermoplastic of composite material shape craft, basically shape to the technology transplants and come by composite material of colophony of hot solid sex and metal. It is OK to differ according to all equipments cent shapes for mould pressing, double film shapes, autoclave shapes, vacuum bag shapes, fiber is twined shape, pressure delay shape etc.

1, double film shapes

Double film shapes to also call colophony film to permeate shape, one kind be ICI company development is used beforehand composite material of dip makings preparation is made method, this law is helpful for an appearance more complex make a processing.

Shape in double film in, had cut out beforehand dip makings is put at two reducible flexible between colophony film and metallic film, velar periphery uses a metal or other data is sealed, in shape in the process, heat to shape after temperature, bring to bear on to shape certainly pressure, make an appearance that has according to metal pattern and be out of shape, final refrigeration finalizes the design.

Double film shapes in, want to will be made commonly be enclosed with film and vacuumize, as a result of alterable form sex of film, the limitation that flows to colophony is far be less than rigid mould, on the other hand, because vacuum issues metabolic film to be able to be opposite,make bring to bear on even pressure, can rise make pressure change degree, assure to shape quality.

2, pull crowded shape

Pull crowded shaping is one kind makes the technique that has constant and sectional composite material profile continuously, use at making one-way fiber enhance the simple product with sectional sincere at first, develop gradually it is OK to become production sincere, hollow and all sorts of complex and sectional goods, and the function of profile can be designed, can satisfy all sorts of engineering construction requirements.

Pull crowded shaping is will beforehand dip is taken (gauze) tie of the solid in crowded mould is helped in a group, dip expects or be the edge plays crowded side beforehand beforehand dip, or it is additional macerate. Common macerate method is fiber blending macerate and macerate of pulverous and liquefacient bed.

3, mould pressing shapes

Mould pressing shapes is had cut through will pressing mould size to cut into parts beforehand the temperature that dip makings sheet heats to fuse to prep above colophony inside heating furnace, send into big tool set next, fast hot pressing shapes. Shape cycle comes a few minutes in a few seconds commonly inside finish. This kind shapes methodological specific power consumption, operating costs all inferior, productivity is tall, it is current thermoplastic the commonnest kind in composite material processing shapes method.

4, twine shape

Thermoplastic the fiber of composite material is twined shape to originally with heat quality the different point of composite material is when twining, want beforehand dip gauze (belt) heat softening point, undertake heating in the osculatory dot of core model.

Normally hot method has conduct heat, interpose report heats, electromagnetism heats, electromagnetism radiate heats etc. Heat in electromagnetism radiate in, the radiate outside differ because of the wavelengh of electromagnetic wave or frequency again and sharing out bonus (IR) , microwave (MW) with radio frequency (RF) heat etc. The last few years still developed laser to heat reach supersonic heat system.

In recent years new-style twine shape craft gets developing, among them one pace shapes law, namely fiber connects powder of overheat plasticity colophony to boil liquefacient bed is made beforehand dip gauze (belt) , twine directly next go up in core model; Still have shape through heating law, be opposite namely carbon fiber beforehand dip gauze (belt) direct electrify, rely on electrify to give out heat make thermoplastic resin is molten, make fiber gauze (belt) wrap product; The 3rd kind is the precision that undertakes voluble rising voluble product with the robot and automation degree, got huge takes seriously consequently.
