MANUFACTURE OF FIBER REINFORCED POLYURETHANE MOLDED PRODUCT

摘要

PURPOSE:To manufacture a fiber reinforced polyurethane molded product by easily and accurately arranging a fiber reinforcing body to the cavity of a mold and injecting a polyurethane raw material in the mold at the time of mold clamping under such a condition that the positional shift of the fiber reinforcing body is hard to generate and the fiber reinforcing body is hard to produce a burr. CONSTITUTION:In the manufacturing of a fiber reinforced polyurethane molded product wherein a fiber reinforcing body 10 is arranged to the cavity 18 of a mold 14 and a polyurethane raw material is injected in the cavity to be integrally molded along with the fiber reinforcing body 10, positioning protruding parts 12 are provided to a part of the outer peripheral edge 11 of the fiber reinforcing body 10 and the outer peripheral edge other than the protruding parts 12 is made same to or smaller than the cavity 18 and the fiber reinforcing body 10 is arranged to the cavity so that the protruding parts 12 of the outer peripheral edge come into contact with the inner wall surface 19 of the cavity under pressure directly or through a skin material 16 to be subjected to integral molding.
