Title:
PHENOLIC RESIN, EPOXY RESIN, CURABLE RESIN COMPOSITION, CURED ARTICLE, FIBER-REINFORCED COMPOSITE MATERIAL, AND FIBER-REINFORCED RESIN MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2022/234776
Kind Code:
A1
Abstract:
Provided is a phenolic resin which is a reaction product of a catechol compound with an ortho-xylylene-skeleton-containing compound, the phenolic resin being characterized by having a catechol skeleton derived from the catechol compound and an ortho-xylylene skeleton derived from the ortho-xylylene-skeleton-containing compound. A cured article which is produced using an epoxy resin produced using the phenolic resin can exhibit high heat resistance and high flexural properties (including flexural strength, a flexural modulus and others), and is therefore used suitably in a fiber-reinforced composite material and a fiber-reinforced resin molded article.
