The present invention discloses a glass fiber reinforced AS material with impact resistance and high temperature resistance, and its preparation method. The formulation of the impact-resistant and high-temperature-resistant glass fiber reinforced AS material comprises: AS resin: 43.2–78.9 parts; reactive monomer: 5–20 parts; crosslinking agent: 0.2–5 parts; initiator: 0.1–1 part; antioxidant: 0.2–0.5 parts; Lubricant: 0.2–0.5 parts; Glass fiber: 15–30 parts; The reactive monomer comprises either α-methylstyrene or N-phenylmaleimide, or a combination thereof, wherein α-methylstyrene is 0–20 parts and N-phenylmaleimide is 0–20 parts; Mix AS resin, α-methylstyrene, N-phenylmaleimide, crosslinking agent, initiator, antioxidant, and lubricant uniformly in proportion, then melt extrude and pelletize using a twin-screw extruder; This approach enhances the impact strength and high-temperature resistance of the reinforced AS system by incorporating poly-α-methylstyrene, crosslinking agents, and initiators while controlling the crosslinking degree. It also improves surface fiber floating and achieves excellent ultrasonic welding performance.
