Abstract

The invention belongs to the technical field of composite material preparation and specifically relates to phosphorus-containing polyaryletherketone capable of increasing interlaminar toughness of a bismaleimide resin based composite material and its toughening film. In allusion to specific technological requirements for preparing a composite material laminate from a bismaleimide resin system by a RTM forming process, an interlaminar-toughening phosphorus-containing polyaryletherketone film which matches the bismaleimide resin RTM forming process is designed. The invention is characterized in that the film is basically not dissolved in the resin system at the bismaleimide resin injection stage so as to maintain a complete film structure and effectively avoid problems such as resin flowing difficulty caused by abrupt increases in viscosity of the resin system due to the film dissolved during the injection process; but at the stage of heating and curing processes after resin injection, the toughening film and the resin matrix undergo dissolution and phase splitting so as to generate the toughening effect, form the interlaminar-toughening structure, raise damage tolerance of the composite material and greatly improve interlaminar toughness of the composite material. Meanwhile, the phosphorus-containing polyaryletherketone has excellent heat resistance, and heat resistance of the composite material will not be influenced.
