Abstract
A molding material structure of a thermoplastic resin composition comprising (1) at least one pillar-shaped body made of a bundle of glass fiber filaments and a non-oriented thermoplastic resin and (2) an outer covering layer of an oriented thermoplastic resin compatible with the resin in said inner body is found to produce molded articles in which glass fiber filaments are dispersed uniformly in the resin matrix with longer average length to improve various properties of molded articles, especially impact strength.
