Description
本発明に係る耐衝撃性繊維強化プラスチックに用いられる高強度繊維としては、引張強度が17cN/dtex以上のものが好ましく、17〜45cN/dtexsのものがより好ましく、19〜40cN/dtexのものがさらに好ましい。また、高強度繊維の弾性率としては、300〜2000cN/dtexが好ましく、350〜1800cN/dtexがさらに好ましい。このような特性を備えた高強度繊維としては、特に限定されるものではなく、例えば、芳香族ポリアミド(アラミド)、芳香族ポリエーテルアミド、全芳香族ポリエステル、超高分子量ポリエチレン、ポリビニルアルコール、ポリパラフェニレンベンゾビスオキサゾール、ポリベンズイミダゾール、ポリイミド、ポリエーテルエーテルケトン、ポリエーテルイミド、ポリフェニレンサルファイド、ノボロイド、ポリピリドビスイミダゾール、ポリアリレート、ポリケトン、ポリテトラフルオロエチレン、ポリオキシメチレン、ポリアクリロニトリル、ポリアミドイミド、ポリエーテルケトンなどからなる繊維、炭素繊維、セラミック繊維、ガラス繊維などが好ましく使用でき、耐衝撃性、生産性、価格などからアラミド繊維、超高分子量ポリエチレン、ポリパラフェニレンベンゾビスオキサゾール、ポリピリドビスイミダゾールがさらに好ましく使用できる。また、これら高強度繊維の繊度としては、100〜7000dtexであることが好ましく、200〜3500dtexの範囲がさらに好ましいが、特に限定されるものではない。
原糸強度20cN/dtex、弾性率500cN/dtexのアラミド繊維(総繊度3300dtex)を使用した平織織布(目付:460g/m2、織り密度17本/2.54cm、厚さ0.64mm)にフェノール樹脂(ポリビニルブーチラール主成分)を含浸、乾燥して樹脂分10wt%のプリプレグを得た。10wt%のプリプレグ7枚、樹脂なし平織織布7枚を交互に積層し、150℃、50kg/cm2 、30分加熱加圧成形して耐衝撃性繊維強化プラスチックを得た。
実施例1のプリプレグの使用し、10wt%のプリプレグを7枚((a)層)と10wt%のプリプレグ4枚、樹脂なし平織織布3枚を交互に積層((b)層)した構成(1)の積層品を実施例1の方法で成形し、耐衝撃性繊維強化プラスチックを得た。
実施例1の10wt%のプリプレグを使用し、プリプレグ6枚積層((a)層)とプリプレグ3枚、樹脂なし平織織布3枚を交互に積層((b)層)、プリプレグ2枚((c)層)積層した構成(2)の積層品を実施例1の方法で成形し、耐衝撃性繊維強化プラスチックを得た。
実施例3の耐衝撃性繊維強化プラスチックにアルミナセラミックス(純度92%、比重3.6g/cm3、重量18kg/m2、大きさ10cmの正方形、厚み5mm)を15cm角の高強度繊維強化プラスチックにウレタン系接着剤で固定し多層構造体を得た。
実施例1の10wt%のプリプレグを14枚積層し、実施例1の条件、方法で耐衝撃性繊維強化プラスチックを得た。
比較例1の高強度繊維強化プラスチックを実施例4のアルミナセラミックスとをウレタン系接着剤で固定し多層構造体を得た。
