Xu Huacheng (Asahi Kasei) devoting oneself to to develop a series of compound thermoplastic colophony material, use at replacing metallic part. One-way adhesive plaster of Xu Huacheng (UD-Tape) it is data of account of a kind of adhesive plaster, by one-way braided carbon fiber enhances polyamide colophony composition. UD-Tape has superior unit weight strength and stiffness and other and outstanding mechanical property, suit to use colophony substitute to replace metallic part in all sorts of products very much, include a car component, electric conduce to in order to reduce product weight with electronic component, plane part, motion and recreational product and housing materials —— decrease carry the greenhouse gas in using a process with the product to discharge. UD-Tape still can solder other thermoplastic on colophony material, and become with note model to shape when offerred outstanding appearance flexibility is united in wedlock, can produce the structure of much material component that has enough strength and stiffness, note model to shape in convention especially below the situation that cannot produce the part that has enough strength and tigidity.
Use check study 2: Shape through insert the intensity insert that enhances the component that note model shapes is a kind of process, in this process, intensity enhances what insert —— passes suppress one kind to shape by UD-Tape or automatic shop belt makes to shape body —— is placed to be inside the mould before noting model to shape, form thereby have inside buy whole intensity increases inject shapes component. The insert that Xu Huacheng checked to carry afore-mentioned UD ring that twine a method to form shapes function. Intensity is extended to measure in 90°C and the tension below 50% relative humidity make clear, ply enhanced the tensile strength of the layer to break up one time almost for the UD-Tape of 0.4 millimeter only.
Use check study 3: The part of component large wall that uses UD-Tape section hot pressing to form complex form and the component that lead costal region can shape through hot pressing UD-Tape section (the rectangular fragment that arises through section or cut UD-Tape) will make. The typical condition that hot pressing shapes: Frit temperature spends 260-280 ℃ , extraction temperature 80-100 ℃ , pressure 3-5MPa, 5-10 of pressurization melt-down time minute) .
