Base material for preform, reinforced fiber preform, fiber reinforced resin molding and method for manufacturing fiber reinforced resin molding

摘要

PROBLEM TO BE SOLVED: To provide a base material for preform, made of fiber-reinforced resin base material having no value for use in design application due to including fiber defects, allowing a molding with excellent designability to be produced.SOLUTION: A base material for preform includes reinforced fiber threads A orientated at least in one direction. At least one surface of the base material includes fiber defects along the orientation of the reinforced fiber threads A. Reinforced fiber threads B are embedded in the fiber defects.SELECTED DRAWING: Figure 1
