Description
本発明による好ましい例示的な樹脂配合物を、表1に示す。室温でエポキシ成分を低分子量ポリエーテルスルホンと混合して樹脂ブレンドを形成し、それを60分間にわたって130℃まで加熱して、低分子量ポリエーテルスルホンに完全に溶解させることによってマトリックス樹脂を調製した。この混合物を80℃まで冷却し、成分の残り(ポリアミドイミド粒子、ポリアミド粒子及び硬化剤)を添加し、完全に混入させ、未硬化樹脂を形成した。
表2に示される配合物を有する比較樹脂を、例1と同じ手法で調製した。樹脂は、低分子量PESを高分子量PESに置き換えたこと以外、例1の樹脂と同じである。
本発明による例示的な樹脂配合物を、表3に示す。マトリックス樹脂は、室温でエポキシ成分をポリエーテルスルホンと混合して樹脂ブレンドを形成し、これを130℃に60分間加熱してポリエーテルスルホンを完全に溶解することによって調製した。この混合物を80℃に冷却し、成分の残り(ポリアミドイミド粒子、ポリアミド粒子、ポリウレタン粒子、及び硬化剤)を添加し、十分に混合して、未硬化樹脂を形成した。
表4に示される配合物を有する比較樹脂を、例2と同じ手法で調製した。樹脂は、低分子量PESを高分子量PESに置き換えたこと以外、例2の樹脂と同等である。
本発明による例示的な樹脂配合物を、表5に示す。未硬化樹脂は、室温でエポキシ成分をポリエーテルスルホン(PES)と混合して樹脂ブレンドを形成し、これを130℃に60分間加熱してPESを完全に溶解することにより調製した。この混合物を80℃に冷却し、硬化剤としてBAPBを添加して、十分混合することによって未硬化樹脂を形成した。
