More Information
Summary:This invention relates to an epoxy resin composition for fiber-reinforced composite materials, which contains the following constituent components (A), (B), and (C). Component (A) contains at least one poly-naphthalene-based epoxy resin, component (B) contains at least one alicyclic epoxy resin and/or a divinylarene diepoxide resin, and component (C) contains at least one amine curing agent. This epoxy resin composition, containing a specific combination of particular types of epoxy resin and curatives, provides high heat resistance and high flexural modulus under extreme environmental conditions. More particularly, a cured resin prepared by the epoxy resin composition offers well balanced mechanical properties that are suitable for preparing fiber-reinforced composite materials useful in aircraft components, spacecraft components, automobile components, artificial satellites components, industrial components, and the like.
