Title:
【発明の名称】長繊維強化熱可塑性樹脂成形体の製造方法及びそれによる製造物
Document Type and Number:
Japanese Patent JP3410462
Kind Code:
B2
Abstract:
A new process for producing a fiber-reinforced thermoplastic resin molded product with a high mechanical strength and no heat substantial deterioration of the resin, by an efficient heating without applying shear stress to the fiber-reinforced thermoplastic resin base material and a molded product, for example, a tiptoe core for a safety shoe produced by said process are provided.The fiber-reinforced thermoplastic resin base material P1 in a string form or a tape form is scattered and accumulated in a vessel such as tube 11, and a heating gas passed to the accumulated base material to melt heat, and preferably press by a plunger 15, the base material P1, whereby a molten mass P2 is formed, and then the molten mass P2 is dislocated to a mold to be press-mold. Said base material preferably satisfies the following formula: {fraction (1/100<=RHO1/rho0<=½, wherein rho0 means a density where said base material is scattered and accumulated and rho0 means a true density of said base material.
