▎ 摘　　要

NOVELTY - Preparation of composite material involves dispersing 0.1-5 pts. wt. mono-layered graphene oxide in 500 pts. wt. solvent, ultrasonically processing, adding 95-99.9 pts. wt. ultra-high molecular weight polyethylene, stirring, drying resultant product, milling, pre-pressing in a flat vulcanizing machine at 4-9 MPa for 10-30 minutes, heat-preserving at 180-250 degrees C for 1.5-3 hours, processing in a lower die at 8-20 MPa, cooling to room temperature, and irradiating with electronic beam or radioactive source of cobalt at exposure dose of 50-150 kGy for 5-9 days. USE - Preparation of composite material (claimed). ADVANTAGE - The method enables preparation of composite material having excellent mechanical property, hardness, tensile strength, frictional resistance and wear resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite material.
