PROCESS AND APPARATUS FOR PRODUCING REINFORCING-FIBER STRIP SUBSTRATE HAVING CIRCULAR-ARC PART, AND LAYERED STRUCTURE, PREFORM, AND FIBER-REINFORCED RESIN COMPOSITE MATERIAL EACH COMPRISING OR PRODUCED USING THE SUBSTRATE

摘要

A process for producing a reinforcing-fiber strip substrate having a circular-arc part includes contacting one surface of a strip-shaped, unidirectional reinforcing-fiber substrate formed by arranging a plurality of reinforcing-fiber strands in one direction in parallel with each other with a flexible member; deforming the unidirectional reinforcing-fiber substrate into a circular-arc shape by deforming at least a part of the flexible member into a circular-arc shape in a direction extending along its contact surface with the unidirectional reinforcing-fiber substrate; and thereafter, separating the flexible member from the unidirectional reinforcing-fiber substrate having been deformed.
