Structural material and process for its production

Abstract

Disclosed is a structural material excelling in lightness of weight, strength, flexural modulus and other properties, being made from polyamide resin reinforced with continuous fiber and/or long filament reinforcing material. This structural material can be fabricated by a monomer casting method by arranging said fiber reinforcing material preliminarily in a desired shape, putting it into a mold, pouring molten ω-lactams containing a polymerization catalyst and an initiator into said mold, and heating to obtain polyamide resin.
