    • Abstract


      A novel matrix resin system, viz. oligoimide-epoxy resin, has been developed to prepare glass-fibre-reinforced composites. Diaminodiphenylmethanebismaleimide-diaminodiphenylmethane (DDMBM-DDM) andp-phenylenebismaleimide-diaminodiphenylmethane (PBM-DDM) oligomers having more-NH2 groups were prepared through Michael addition reaction. These oligoimides were used for curing commercial epoxy resin (i.e. diglycidyl ether of bisphenol A) at 120–140°C to fabricate crosslinked oligoimide-epoxy resin glass-fibre-reinforced composites without evolution of byproduct. The fabricated composites (i.e. laminates) were characterized by their chemical resistance and mechanical properties.
