Carbon fiber reinforced plastics

…Composite materials in which the continuous phase is plastic or plastic-like. Representative 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 similarly use carbon fibers. Both have high specific elastic modulus (elastic modulus/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. …

…連続相を形成する相がプラスチックまたはプラスチック状になっている複合材料。代表例は，繊維強化プラスチックfiber reinforced plastics(FRPと略称)で，ガラス繊維の長繊維，織布，短繊維等を不飽和ポリエステル樹脂やエポキシ樹脂などの熱硬化性樹脂で固めたガラス繊維強化熱硬化性プラスチックglass fiber reinforced plastics(GFRPと略称)，同様にカーボン繊維を使った炭素繊維強化熱硬化性プラスチックcarbon fiber reinforced plastics(CFRPと略称)で，ともに比弾性率(弾性率/密度)や比強度(強度/密度)が高いことを利用して，軽量，高強度，高剛性が要求される宇宙航空材料，スポーツ用品等に幅広く普及しつつある。一方，マトリックス樹脂がポリプロピレン等の熱可塑性樹脂の場合は，おもに短繊維状のガラス繊維や炭素繊維を用いて射出成形し，これを繊維強化熱可塑性プラスチックfiber reinforced thermoplastics(FRTPと略称)と呼び，おもに機械部品等に金属代替として使用されつつある。…
