<p>A process for producing a fiber-reinforced resin which comprises placing at least a reinforcing fibrous base in the cavity of a mold, injecting a resin into the cavity, and curing the resin, characterized in that a substrate for skin layer formation and a resin-diffusing medium in which the proportion of the coefficient of impregnation thereof to that of the substrate for skin layer formation is 1.5-10 are disposed on at least one side of the reinforcing fibrous base through an interlayer comprising at least one woven fabric having a cover factor of 90-100% so that the resin-diffusing medium is located between the substrate for skin layer formation and the reinforcing fibrous base. The process diminishes pin hole generation in the skin layer in RTM, and can reduce the necessity of a repair step in, e.g., a coating step as a later step. It can attain improved productivity. ® KIPO & WIPO 2009</p> |
