The present invention relates to the field of thermoplastic composites, specifically disclosing a high-performance long glass fiber reinforced thermoplastic composite comprising the following components by weight: thermoplastic resin 100-120 parts; surface-modified long glass fibers 30-40 parts; antioxidant 1-2 parts; UV absorber 0.9-1.2 parts; additives 4-6 parts. The invention further discloses a preparation method for the high-performance long glass fiber-reinforced thermoplastic composite material, comprising the following steps: feeding thermoplastic resin, surface-modified long glass fibers, antioxidant, UV absorber, and additives into the main feed port of a co-rotating parallel twin-screw extruder; uniformly melt-mixing the materials; extruding through a die; cooling, drying, and pelletizing to obtain the long glass fiber-reinforced thermoplastic composite material. The present invention enhances the bond strength between glass fibers and plastic, preventing the occurrence of “fiber floating” in the mold.
