The invention discloses a high performance UHMWPE composite material and a preparation method thereof. The high performance UHMWPE composite material is characterized by being prepared from followingcomponents in percentage by weight: 70-98% of UHMWPE, 1-30% of modified inorganic particles, and 0.05-2% of antioxidant. According to the preparation method, UHMWPE is taken as the matrix, modified inorganic particles and a little amount of antioxidant are added, and then the mixture is moulded to obtain the composite material. The prepared UHMWPE composite material has a high tensile strength; only 1 wt% of inorganic particles and antioxidant, the tensile strength is doubled; at the same time, the thermal deformation temperature is increased, the wear resistant performance is enhanced, the interface of the composite material is strengthened, compared with a conventional coupling agent, the composite material is environmentally friendly, the processing is promoted, furthermore, the cost islow, the preparation technology is simple, and industrialization can be realized.
