熱可塑性ポリイミドを用いた平織CFRP積層板における樹脂含浸挙動

抄録

This study focuses on thermoplastic resin impregnation behavior in carbon fiber reinforced thermoplastic polyimide (CFRTP). The objective of the present study is to clarify the relationship between molding conditions and resin impregnation to fiber bundle and the effect of resin impregnation on the mechanical properties of the composites. Specimens were prepared using micro-braiding, film stacking and powder methods. The analytical prediction for resin impregnation showed a good agreement with the impregnation ratio experimentally-obtained. In addition, the void content inside the fiber bundle could be drastically reduced by pressurized cooling.
