Description

Technical field [0001] The invention belongs to the technical field of composite materials and provides a polyesterimide / bismaleimide resin composite material and a preparation method. Background technique [0002] Bismaleimide resin is a type of resin system derived from polyimide resin system. It is a bifunctional compound with maleimide as the active end group. Its resin has similar fluidity to typical thermosetting resins. And plasticity, it can be processed and formed by the same general method as epoxy resin. At the same time, it has the characteristics of high temperature resistance, radiation resistance, moisture resistance and corrosion resistance of polyimide resin. In general, bismaleimide resin has good high temperature resistance, radiation resistance, humidity resistance and low water absorption. As a high-strength, high modulus and relatively low density advanced composite resin, it has been used in aerospace It has been widely used in many industries such as indu...
