摘要： A composite material for a lateral rigid member of a track belt for use in a snowmobile. A glycidylamine epoxy resin that is a polyfunctional epoxy thermosetting resin and has a molecular weight of about 250 to 1000 is included in an amount of 100 parts by weight. A 2-functional epoxy resin having a molecular weight of about 100 to 600 is included in an amount of 12 to 14.5 parts by weight. An aromatic polycarbonate thermoplastic resin having a molecular weight of about 12000 to 80000, a glass transition point of 130.degree. C. or more, a melting point of 220.degree. C. to 240.degree. C. is included in an amount of 5 to 45 parts by weight. An acid anhydride curing agent is included in an amount of 90 to 130 parts by weight. The composite material also includes reinforcing fiber.
