Modification of epoxy resin with reactive end-capped carboxylic imide oligomer for manufacture of glass-fiber reinforced composite

The present work aims at preparing glass-fiber reinforced epoxy resin composite modified with reactive end-capped carboxylic imide oligomer. The carboxylic imide 2,2-bis[4-(4-aminophenoxy)phenyl propane (CIBAPP) oligomer was synthesized via two-step polycondensation of 2,2-bis[4-(4-aminophenoxy)phenyl propane (BAPP) diamine and trimellitic anhydride (TMA), then the oligomer was characterized by FTIR spectrum and solubility test. The oligomer was...
