Fiber reinforced polyamide resin composite material and method of manufacture thereof

摘要: A fiber reinforced polyamide resin composite material is suitable for use as a molding material. liquid lactam added with an anionic polymerization catalyst and another activator are supplied to impregnation chamber while being mixed together at predetermined or selected ratio. In the chamber, long reinforcing fibers impregnated form strand. Then coating layer of thermoplastic continuously formed all over outer peripheral surface strand, after which strand introduced into heated in fibers. The cut pellets length without removing layer. manufactured by this method has high adhesive strength between provides excellent physical properties ultimate moldings.
