The invention discloses a thermoplastic composite material as well as a preparation method and application thereof. The thermoplastic composite material comprises a surface layer material and a framework material, wherein the surface layer material is prepared from the following components in parts by weight: 30 to 50 parts of high-fluidity polypropylene resin, 45 to 50 parts of untwisted continuous glass fiber, 1 to 8 parts of a compatilizer, 0.5 to 1 part of a lubricant, 1 to 2 parts of an antioxidant, 1 to 8 parts of a highlight improver and 1 to 2 parts of carbon black; the framework material is prepared from the following components in parts by weight: 20 to 35 parts of medium-high fluidity polypropylene resin, 50 to 70 parts of untwisted continuous glass fiber, 1 to 8 parts of a compatilizer, 0.5 to 1 part of a lubricant, 1 to 2 parts of an antioxidant, 1 to 12 parts of a low-warpage improver and 1 to 2 parts of carbon black. The thermoplastic composite material provided by the invention not only has good mechanical properties, but also has high surface gloss, high strength, low warpage and high temperature resistance, can meet the requirements of automobile engine cover materials, and realize light weight modification of automobiles at the same time.
