Abstract
A light-weight composite material having a laminated structure comprises at least one porous fiber layer constructed of reinforcing short fibers which are distributed in random directions and combined with each other mainly at intersections thereof by carbonized binder and at least one fiber reinforced plastic layer comprising reinforcing fibers and a matrix resin. The composite material can have a low density, high mechanical properties of strength, modulus of elasticity and rigidity.
