Abstract: Provided are a fiber-reinforced composite molded article prepared by heat-curing, as a molding material of a fiber-reinforced resin material, a resin composition to which an internal mold release agent is added, the fiber-reinforced composite molded article being capable of effectively producing mold releasability even with a small amount of the mold release agent added, and being capable of achieving high productivity, and a method of forming the fiber-reinforced composite molded article. A fiber-reinforced composite molded article prepared by curing reinforcing fibers and a resin composition, the resin composition including an internal mold release agent, wherein the value obtained by normalizing a Poisson-corrected ion intensity derived from the internal mold release agent detected on the surface of the fiber-reinforced composite molded article, by the Poisson-corrected gross positive secondary ion intensity detected in the predetermined area is higher than 0.1, and a molding method therefor.

Abstract: A fiber-reinforced composite molded article which is obtained by molding reinforcing fibers and an epoxy resin, while containing a silicone oil as an internal mold release agent, and which is characterized in that the fragment ion intensity ratio A/B as detected in case where the molded article surface is analyzed by time-of-flight secondary ion mass spectrometry is expressed by the relationship of 3?A/B?20. A: The intensity of a fragment ion that has the highest intensity among the fragment ions derived from the silicone oil. B: The intensity of a fragment ion that has the highest intensity among the fragment ions derived from the epoxy resin.
