Successive fiber increases thermoplastic composite material performance is superior, as advocate bear force or second bear force structural member has the light qualitative excel in, character that can design unifinication of gender, fatigue resistance and structural function, very large application latent capacity is had in the domain such as traffic of aerospace, orbit, car. And composite material shapes namely by the critical process measure of structural member of raw material translate into craft, successive fiber increases thermoplastic composite material structural member shapes the condition of raw material can divide craft basis to shape for the liquid craft, thermoplastic beforehand dip makings shapes craft and fiber are jumbly craft. Among them, the liquid shapes craft basically includes thermoplastic matrix colophony delivers moulding (T-RTM) craft, former pull crowded craft to wait; And thermoplastic beforehand dip makings shapes craft incorporates autoclave craft, mould pressing technology, twine craft to wait; Fiber is jumbly craft is preparation and the colophony fiber that enhance fiber diameter to comparative, make two kinds of fiber jumbly next into a kind of compound gauze, eventually finished product of mould pressing preparation. It is will thermoplastic that mould pressing of of craft of 01 mould pressing shapes beforehand after dip makings cuts out the shop is folded, in putting a pattern, warm up heat, wait for warm up to shape after temperature, be opposite through press beforehand dip makings lay up undertakes pressurization, solidify gets satisfaction the goods of the requirement eventually. To a few complex features, installation reach reinforcement, use mould pressing shapes to come true very hard, because mould pressing appears to combine those who note model on this market,shape craft, the FiberForm craft of the Organomelt craft that is like ENGEL, Kelaosimafei. Compound sheet mixes FiberForm craft —— of Kelaosimafei one-way board heat shapes and photograph of the rear craft that note model is united in wedlock, the function that realizes height is compositive, applicable is prevented at module of bracket of seat bracket and back of a chair, dashboard, door, flank strike the part such as bracket of protector, accumulator. Kelaosimafei was in the United States 2018 Orlando is plastic exhibit on, second spectacular this equipment and technology. of 02 pulls crowded craft crowded shape craft is the successive fasciculus fluid of macerate colophony glue, belt or cloth, below the action of traction, shape through extruding mould, solidify, produce the profile that length is not restricted continuously. Thermoplastic composite material helps crowded technology, basis beforehand dip technology can be divided squeeze to be not reaction to pull shape to be pulled with reaction crowded shape two kinds big. Company of France CQFD was developed former help crowded technology, namely fiber gauze or fabric fall in outside force drawing, infiltration after monomer of amine of the acyl inside oneself and initator, in finalize the design shape inside the mould and heat aggregate, make a product eventually. The fiber bulk mark of the goods that this craft shapes can be achieved 70% , quantity of model of the drawing on fiber direction can achieve 60 GPa(to enhance fiber for fibre glass) , have admirable mix than intensity the quantity that compare a pattern. What this one craft application develops together at French CQFD company and those Europe company, contemporary car is thermoplastic composite material is prevented bump into bridge, its main body shapes use former help crowded technology, does material enhance PA6(trade name to be C-SHOCK for successive fibre glass character? ) , note model craft through wrapping Fu subsequently, introduce prevent the installation that hits bridge to nod, whole program photograph decreases heavy 43%(3 than metallic plan. 7 Kg) . of 03 is twined shape is twined shape craft is first macerate resinous successive fiber warm-up, twine core model to go up, heat continuously in voluble process, repass applies force to make beforehand dip makings frit is received for an organic whole, chase an agglutinate, refrigeration hind gets corresponding component product. Thermoplastic of composite material twine shape can use beforehand dip fiber or beforehand dip belt undertakes. of craft of T-RTM of of of 04 delivers moulding (RTM) craft enhances hot solid sex in successive fiber the application in the preparation of composite material is wide; Colophony of hot solid sex is in not before solidify, viscosity is inferior, can enter fiber space easily and infiltration fiber. And thermoplastic polymer because viscosity is big, implement RTM technology very hard. Kelaosimafei initiates sexual ground to use pattern of polymer monomer infuse, make monomer aggregate inside the mould, implemented technology of thermoplastic RTM craft ——T-RTM. The principle of T-RTM craft is a dip have ε- of mixture of active of amine of the acyl inside oneself shape partly fabric shapes beforehand, it is directly in the mould polymerization is ripe change nylon - 6. Exhibit in 2016 K on, overcome Lao Sima to poor the roof crust frame of racing bike of Roding Roadster R1 that revealed use T-RTM craft to shape. Notable is: This component used fibre glass at the same time (white) serve as with carbon fiber enhance material, assembled metallic insert in an organic whole in the mould. Autoclave of of craft of autoclave of of 05 shapes is monolayer beforehand dip makings presses the composite material preform that books directional shop to be folded to be put inside autoclave, solidify process is completed below constant temperature and pressure. Autoclave is one kind can bear with adjusting control the special pressure vessel of limits of constant temperature, pressure. Preform is put in the mould surface with agent of drawing of patterns by the shop, next ordinal with poriferous prevent stick cloth (film) , felt suction glue, breathe freely felt is enclothed, inside empty bag of sealed Yu Zhen, put into autoclave again. Before adding lukewarm solidify first bag vacuumize, eliminate air and volatile, warm up by system of different resinous solidify next, pressurization, solidify. Of solidify system make with carrying out is to make sure autoclave shapes the key that makes a quality. This kinds shape craft applies to cover of production plane port, commutate, airborne radar cover, the product such as bracket, wing, empennage. Other of of 06 besides afore-mentioned craft, successive fiber increases thermoplastic polymer base high-powered composite material still can use compound macerate - the low cost unifinication that the 3D of melt deposit prints craft to implement component part of composite material of high-powered complex structure is made quickly.
