Description
間においてCSCNT7の端部が楔効果を発揮することで両者の結合が強固とな
り、これにより繊維体3間の層間せん断強度が向上する。
及び外周面cの間)には間隙が存在し、これにより、外部から応力が加わった場
合、応力吸収が行われるため、座屈し難い。よって、複合材料とした場合に圧縮
強度が向上すると考えられる。
差を持たせることで、プリプレグ5と樹脂シート6とを積層して硬化成形により
樹脂が溶融した際、CSCNT7が高濃度側から低濃度側へと移動する。これに
より、上記楔効果をプリプレグ5と樹脂シート6との境界部分でも効率良く発現
させることが可能となる。
樹脂の組成を同一とした場合には、複合材料中で相分離が生じ難くなり、それだ
け剥離強度を向上させることが可能となる。
A:主剤 ノボラック系エポキシ樹脂若しくはビスフェノールA型エポキシ樹脂
B:硬化剤 ジシアンジアミド(主剤を硬化させるものであれば特に制限はない。)
C:硬化促進剤 DCMU若しくはイミダゾール(主剤を硬化させるものであれば特に制
限はない。)
本実施例においては、ビスフェノールA型エポキシ樹脂とジシアンジアミドとDCMUとから成る樹脂組成物が採用されている。
に対して10wt%となるように添加して、攪拌混合する。
その後、75℃×0.5hで加熱しながら攪拌する。
inで更に加熱しながら攪拌する。
