PURPOSE:To manufacture a reinforced fiber sheet of excellent handling properties for obtaining a fiber reinforced resin material of high performance by interlace thermoplastic fiber with reinforced fiber arranged in the fiber direction and integrating therein. CONSTITUTION:Short fiber-like thermoplastic polymer fiber is interlaced into a web composed of reinforced fiber arranged substantially in the fiber direction and confounded integrally. The shape retaining properties and handling properties of a sheet are superior by said arrangement, and laminate density of a laminate composed of laminated sheets is high. The filling density of sheets into a mold cavity can be enhanced accordingly. Because of the liquid absorption effect of an interlaced section of composite sheet and the liquid suction effect along the arranged fiber, impregnation and infiltration into a composite sheet void volume section of an injected reactive liquid raw material injected in the mold cavity are superior. Therefore, uneven fiber containing rate, warp of a molded body and poor dimension stability are hard to be generated, and a sophisticated, large thin-walled or thick-walled molded body of even quality can be manufactured stably. |
