Document Type and Number:
WIPO Patent Application WO/2019/151174
Kind Code:
A1
Abstract:
Provided is a means by which pultrusion can be continuously performed at high speed and the generation of resin residues that adhere to the inner surface of a mold can be suppressed. The present invention also provides a method for producing a fiber-reinforced molded article, wherein a resin-impregnated fibrous base material obtained by impregnating a reinforcing fiber aggregate of reinforcing fiber bundles with an epoxy resin composition is passed through a pultrusion region and pultruded into a predetermined shape by heat-curing the epoxy resin composition, and the epoxy resin composition contains at least components A to D below. A: An aminophenol-type epoxy resin. B: An acid anhydride having a nadic anhydride structure and an acid anhydride having a hydride structure of a phthalic anhydride. C: At least one filler selected from among a silicon compound, a magnesium compound, a calcium compound, an aluminum compound, and inorganic carbon, and having a Mors hardness of 3 or less. D: A release agent.
