ISOTOPIC FIBER-REINFORCED THERMOPLASTIC RESIN SHEET, AND PROCESS FOR PRODUCTION AND MOLDED PLATE THEREOF |
摘要 |
An isotropic fiber-reinforced thermoplastic resin sheet wherein a chopped strand prepreg comprising a thermoplastic resin and a reinforcing fiber is layered so that the fiber orientation is random, the prepreg having a fiber volume fraction (Vf) of 20% to 50%, a length in the fiber axis direction of 15 to 45 mm, and a thickness of no greater than 0.13 mm, and the layered material is molded into sheet form by heating and pressing, and a molded plate obtained from the isotropic fiber-reinforced thermoplastic resin sheet. Even if the volume fraction of the reinforcing fiber is relatively low, a fiber-reinforced thermoplastic resin sheet and a molded plate that are excellent in terms of mechanical properties and their uniformity can be obtained. |
