Abstract
Three new types of heat resistant epoxy resins were developed for advanced fiber reinforced plastic composites. These resins include highly crosslinked glycigyl phenol (PGP), novolac epoxy containing naphthalene rings (PGN), and epoxy containing imide rings (PGI). All of them are highly heat resistant up to 200°C r and are cured under conditions similar to those for conventional epoxy resins. The composite materials in which the developed epoxy resins are used are excellent in heat resistance and also in mechanical properties.
