FIBER-REINFORCED RESIN SHEET AND METHOD FOR MANUFACTURING SAME

Provided is a fiber-reinforced resin sheet with increased productivity. A method for manufacturing a fiber-reinforced resin sheet includes: a step in which cellulose fibers， moist heat adhesive binder fibers that， by reaction with heat and water， can self-adhere or adhere to other fibers， and fine fibrous cellulose are subjected to papermaking by a wet papermaking method and the cellulose fibers are made to mutually adhere by the moist heat adhesive binder fibers to form sheet-shaped base paper; and a step in which the sheet-shaped base paper is impregnated with a resin to form a fiber-reinforced resin sheet. Due to this configuration， it is possible to carry out the previously difficult process of impregnating sheet-shaped base paper， for which cellulose fibers have been used， with resin. Specifically， the problem that impregnation of resin becomes impossible due to high compactness can be solved by including water-retaining fine fibrous cellulose， increasing wettability and making it possible for the moist heat adhesive binder fibers to react. As a result， the resin can be disposed in the cellulose fibers without gaps in order to strengthen the cellulose fibers， and the strength and the reliability of the fiber-reinforced resin sheet as a whole are increased.
