The curing kinetics of mod ified tetraglycidyld iam inod iphenylmethane heat resistant epoxy resin is stud ied. The properties of the resin and carbon fiber composites are analyzed. W ith the help of dynam ic mechanical thermal analysis (DMTA ), the hot mechanical properties of the resin and composites are exam ined. The result shows that the gel temperature of this resin is close to cure temperature. The resin can be used as the matrix of pul- truded composites, which possess excellent heat resistant property and glass transition temperature (Tg) can reach up to 210℃.
