fiber reinforced thermoplastic

Japanese: fiber reinforced thermoplastic（英語表記）fiberreinforcedthermoplastic

...In addition to thermosetting resins, thermoplastic resins such as polypropylene, ABS resin, nylon, and polybutylene terephthalate may also be reinforced with 5 to 50% glass fiber to improve rigidity, dimensional stability, and heat distortion temperature. Also known as FRTP (short for fiber reinforced thermoplastic), it has become common in electrical and automotive parts in recent years. The properties of typical reinforcing fibers and reinforced plastics are shown in Tables 1 and 2, respectively. ...

From [Plastic Composite Materials]

...Typical examples are fiber reinforced plastics (abbreviated as FRP), which are made by solidifying long glass fibers, woven fabrics, and short glass fibers with thermosetting resins such as unsaturated polyester resins and epoxy resins, and carbon fiber reinforced thermosetting plastics (abbreviated as GFRP), which are made by similarly solidifying long glass fibers, woven fabrics, and short glass fibers with thermosetting resins such as unsaturated polyester resins and epoxy resins. Both have high specific elasticity (elasticity/density) and specific strength (strength/density), and are becoming widely used in aerospace materials and sports goods that require light weight, high strength, and high rigidity. On the other hand, when the matrix resin is a thermoplastic resin such as polypropylene, it is mainly injection molded using short glass fibers or carbon fibers, and this is called fiber reinforced thermoplastics (abbreviated as FRTP), which is mainly used as a metal replacement in machine parts, etc. In addition, plastics with dispersed carbon black, calcium carbonate, magnetic powder, etc. are called particulate filled plastics (abbreviated as PFP), and have been developed for special purposes such as electrical conductivity, low combustion energy, and electromagnetic wave absorption.
