Abstract
A high heat-resistant composite material which comprises a polymerizable composition comprising a bi-functional epoxy compound, a tri- or more-functional epoxy compound and a polymerization initiator, wherein the polymerization initiator comprises a sodium salt or potassium salt of mono- or poly-functional carboxylic acid, and a reinforcing fiber such as a carbon fiber or a glass fiber; and a vehicle member or a construction member comprising the above heat-resistant composite material. Said composite material comprises an epoxy polymer having high heat-resistant physical properties over those of a conventional epoxy polymer as a matrix, and exhibits an extremely high retention factor of storage modulus at high temperature.
