An aromatic diamine DADP-30 was used to modify maleimide resin(TMI). The modified maleimide resin was used to react with multi-functional group epoxy resin(TGBAPOPP), and then a solvent-free epoxy matrix resin with high temperature resistance was prepared through adding reactive diluent CE-793-250 and curing agent methyl tetrahydrophthalic anhydride(MTHPA). Its viscosity, gel time,surface energy, and water absorption were studied. The results show that the matrix resin has excellent comprehensive performanc...
