PURPOSE:To manufacture a colored sheet material of superior appearance and mechanical strength and good molding properties by mixing respectively specified quantities of thermoplastic synthetic resin powder, inorganic fiber bundles of specified length or longer, a pigment and viscous liquid of specified viscosity almost uniformly, heating a mixture thus prepared at the temperature of melting point or softening point of thermoplastic synthetic resin and pressurizing. CONSTITUTION:100 pts.wt. of thermoplastic synthetic resin material, 2-300 pts.wt. of inorganic fiber bundles of 2mm long or longer, 0.01-5 pts.wt. of a pigment and 0.5-20 pts.wt. of viscous liquid of 10-100000 centipoise are mixed and agitated almost uniformly, and a mixture thus prepared is heated at the temperature of the melting point or softening point or higher of thermoplastic synthetic resin and pressurized to manufacture a colored fiber reinforced material. Glass fiber and carbon fiber are typical inorganic fibers. As thermoplastic synthetic resin, polyolefin resin, polyamide resin or the like is used, and the average grain diameter is preferably 2mm or less. When the average grain diameter is beyond 2mm, powder is settled by its own weight and sometimes a uniform mixture cannot be prepared. |
