Abstract: For the purpose of stable transmission,lightening self-weight,shock absorption,noise reduction,corrosion resistant,wear resistance,self-repair,and cost reduction,the gear is made of composite materials in stead of metal ones. By designing formulation and using optimized production technology,performance test and research were made on the properties of composite materials. The results showed that the main properties of composite materials used in these gears meet the state requirements. This study showed that the technology is feasible.

Key words: gear, composite materials, performance test
