Abstract
A thermoplastic composite plate material having a quasi isotropy comprises a thermoplastic resin having a melt viscosity of 1,000-15,000 poise and strip pieces each constructed of unidirectionally orientated reinforcing fibers and each having the specific dimensions of the thickness, the width, the length and the ratio of the width and the length thereof. The strip pieces are randomly distributed in plane parallel to a surface of the composite plate material. Since the composite plate material has good quasi-isotropic and high mechanical properties such as flexural strength, flexural modulus and impact strength, a composite product having good quasi-isotropic and high mechanical properties can be obtained by using the composite plate materials. Moreover, since the composite plate material has a good fittability, a composite product having a complicated shape can be easily molded.
