advanced composite material

…In recent years, lighter and stronger materials have been required for aerospace and military applications, as well as in the field of sporting goods, and reinforced plastics that surpass steel and aluminum have been developed. In other words, plastics reinforced with strong and highly elastic carbon fibers and fully aromatic organic fibers (such as aramid fibers) are called advanced composite materials (ACMs). 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. …

[Synthetic resin]

However, the first oil crisis in 1973 and the second in 1979 caused problems with the connection to oil, and the disposal of large amounts of discarded plastic waste has also become an issue. Future growth directions for synthetic resins include engineering plastics, which can be used in small quantities to take advantage of their functions, and ACM (advanced composite material, an advanced composite material reinforced with carbon fiber, etc.), a type of reinforced plastic that is stronger and lighter than steel or aluminum for the purpose of energy conservation.

Japanese:

…近年,より軽く,より強い材料が航空・宇宙・軍事用途をはじめ,スポーツ用品分野にも要求されるようになり,鉄,アルミニウムを超える強化プラスチックが開発されてきた。すなわち,強くて弾性率の高い炭素繊維,全芳香族有機繊維(アラミド繊維など)などで強化されたプラスチックであり,先進複合材料advanced composite material(略称ACM)と呼ばれる。なお,熱硬化性樹脂のほか,ポリプロピレン,ABS樹脂,ナイロン,ポリブチレンテレフタレートのような熱可塑性樹脂にも,剛性向上,寸法安定性向上,熱変形温度向上のために5~50%のガラス繊維が補強される場合がある。…

【合成樹脂】より

… しかしながら,1973年の第1次,79年の第2次オイル・ショックを通して,石油との結びつきが問題になり,また大量に使いすてられるプラスチック廃棄物の処理も問題となってきている。今後の合成樹脂の伸びる方向として,少量でも機能を生かして用いられるエンジニアリングプラスチックとか,省エネルギーのために,鉄やアルミニウムより強くて軽い強化プラスチックの一種ACM(advanced composite materialの略称。炭素繊維などで補強された先進複合材料)などが注目されている。…
