摘要:
A xylylenediamine-based polyamide resin/fiber composite material and molding are provided that do not exhibit a decline in properties under high temperatures and high humidities, and that exhibit a high elastic modulus and present little warping, and exhibit better recycle characteristics, a better moldability, and a better productivity than for thermosetting resins. The polyamide resin-type composite material comprises a fibrous material (B) impregnated with a polyamide resin (A) wherein at least 50 mole % of diamine structural units derived from xylylenediamine, and having a number-average molecular weight (Mn) of 6,000 to 30,000, and containing a component of a molecular weight of not more than 1,000 at 0.5 to 5 mass %.
