UNIDIRECTIONAL PREPREG, FIBER-REINFORCED THERMOPLASTIC RESIN SHEET, METHODS OF PRODUCING UNIDIRECTIONAL PREPREG AND FIBER-REINFORCED THERMOPLASTIC RESIN SHEET, AND, MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a fiber-reinforced thermoplastic resin sheet having both high strength and moldability, a unidirectional prepreg capable of providing such a fiber-reinforced thermoplastic resin sheet, and a method of producing the unidirectional prepreg.SOLUTION: An opened reinforced fiber and a unidirectional prepreg are provided. The unidirectional prepreg is tape-shaped and includes a polymer of a bisphenol A type epoxy resin compound represented by formula (1) with a bisphenol compound selected from among bisphenol A, bisphenol F, bisphenol S, bisphenol B, bisphenol E and bisphenol P, wherein the polymer has a weight average molecular weight of 5,000-25,000, and the average number of the reinforced fiber in the thickness direction of the unidirectional prepreg is 10 or less. In the formula (1), n represents an integer of 1 to 4.SELECTED DRAWING: Figure 1
