The invention relates to a novel plastic-base enhanced foaming composite material which is prepared from the following raw materials in parts by weight: 100 parts of thermoplastic resin, 20-50 parts of continuous fiber, 5-10 parts of filling, 2-8 parts of foaming agent, 2-8 parts of compatilizer, and 0.1-1 parts of processing aid. The invention also discloses a preparation method of the novel plastic-base enhanced foaming composite material, and applications of the material in the preparation of a cue and a table tennis bat. Compared with the prior art, the novel plastic-base enhanced foaming composite material provided by the invention can be directly injection-molded, and the obtained product has the advantages of pretty high strength, pretty high modulus, good toughness, good wear resistance, simple molding and the like.
