METHOD AND APPARATUS FOR MANUFACTURING FIBER REINFORCED RESIN SHEET

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a fiber reinforced resin sheet capable of enhancing the impregnation properties of a resin paste with a reinforcing fiber material after the sheetlike reinforcing fiber material is laminated on the coated resin paste or the cut pieces of a glass fiber are infiltrated in the resin paste. SOLUTION: In an air bubble discharging process, air bubbles are discharged using a roll which has a plurality of almost sheetlike protruded parts and is constituted so that the leading end parts of the protruded parts are discontinuously arranged with respect to the circumferential and axial directions.
