Abstract
A thermoplastic polymer-based composite material and a preparation method thereof are provided. The thermoplastic polymer-based composite material is obtained by impregnating a reinforcing material with a mixture or oligomer of an epoxy resin, a bismaleimide resin, and a bifunctional amine (calculated based on active hydrogen), and then performing an in-situ polymerization. The thermoplastic polymer-based composite material has excellent impregnation effect, excellent secondary processing performance, relatively high heat resistance, excellent flame retardancy, and mechanical properties, and excellent comprehensive performance.
