Abstract
The method produces a fiber-reinforced molded body comprising a matrix resin, reinforcing fibers and hollow particles. The method comprising: producing hollow particles, preparing a resin composition containing the hollow particles thus obtained, the matrix resin and the solvent, and impregnating the reinforcing fibers with the resin composition. In the method during subjecting the suspension to the polymerization reaction, when a polymerization conversion rate of the first polymerizable monomer reaches 93% by mass or more, a second polymerizable monomer having a solubility of 0.3 g/L or more in distilled water at 20° C., is added to the suspension, and the suspension is further subjected to a polymerization reaction.
