In this paper,a polyarylene ether nitrile-based basalt fiber-reinforced composite material (PEN/BF) was prepared by twin-screw extrusion injection molding technology.The effects of adding basalt fibers with different contents on the mechanical and thermal properties of the composites were studied by universal materials testing machine,thermogravimetric analyzer and dynamic thermomechanical analyzer,and the surface morphology and friction and wear properties of the materials were tested and analyzed by scanning electron microscope and friction and wear testing machine.The results showed that the mechanical properties,thermal properties and wear resistance of polyarylene ether nitrile-based basalt fiber composites were greatly improved compared with those of polyarylene ether nitrile-based matrix materials by adding basalt fibers.
