▎ 摘　　要

NOVELTY - Aircraft engine timing gear chain material comprises 20-30 pts. wt. extruded fiber, 3-6 pts. wt. rare-earth ore, 2-6 pts. wt. manganese-zinc alloy, 3-6 pts. wt. graphene powder, 1-3 pts. wt. electric stone powder and 30-50 pts. wt. aluminum alloy. USE - Used as aircraft engine timing gear chain material. ADVANTAGE - The chain material has small expansion and contraction coefficient and improved service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aircraft engine timing gear chain material comprising (i) adding all raw materials into a container and stirring uniformly, injection into the grinding tool and then heating the mixture into a molten state to obtain mixture A, and (ii) allowing the mixture A to stand for 10-15 minutes and cooling to room temperature to obtain final product.
