ABSTRACT:
A fiber-reinforced plastic product comprises a first member which is formed by pressing from a sheet molding compound made of an unsaturated polyester resin and having a first portion which should be reinforced and a second portion having an area adjacent to the first portion, a second member made of a uni directional sheet molding compound made of the unsaturated polyester resin, including a bundle of glass fibers which is continuously formed so as to be arranged in the same direction, and overlayed on the first portion by the press formation, and a concave portion formed in the area. Thereby, the second member is prevented from expanding along the first member during the press formation.
