PRODUCTION OF FIBER REINFORCED PLASTIC MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To produce a fiber reinforced plastic molded product having no air bubbles in its laminate structure and enhanced in strength, productivity and durability. SOLUTION: A gel coat forming process for forming a gel coat 3 at a mold 2 having a corner part l and a laminate forming process for spraying reinforcing fiber bundles 4 longer than the circular arc length of the corner part and a thermosetting resin 5 to the gel coat 3 to form a laminate 6 are provided, and either one of the viscosity of the thermosetting resin 5 specifying the tackiness of the thermosetting resin 5, a spraying speed, the length and thickness of the reinforcing fiber bundles 4 specifying the elastic recovery of the reinforcing fiber bundles 4 and the circular arc length of the corner part 1 is adjusted to make the tackiness of the thermosetting resin 5 larger than the elastic recovery of the reinforcing fiber bundles 4.
