Abstract
A low viscosity epoxy resin, i.e., a low viscosity polyglycidyl derivative, of an aminophenol having at least one alkyl group on its aromatic ring of which viscosity is 15 poises or below as measured at 25.degree. C., a resin composition containing said resin, and a fiber-reinforced composite material containing as matrix a cured product of said epoxy resin composition and a fiber as reinforcing material.
Claims5
An epoxy resin obtained by reacting an aminophenol represented by the general formula ##STR16## wherein R1 represents a hydrogen atom or an alkyl group of 1 to 4 carbon atoms and R2 represents an alkyl group of 1 to 4 carbon atoms, with an epihalohydrin.
