摘　　要：基于对风力发电机制动片现用摩擦材料的分析,研制了纤维增强复合材料,并利用分离式霍普金森压杆试验装置和MM—1000磨粒磨损试验机,研究制动片摩擦材料的冲击性能和耐磨性能。通过对铜基粉末冶金、颗粒增强复合材料、纤维增强复合材料的应力-应变和摩擦性能比较和分析,得出纤维增强复合材料具有较好的耐冲击性能和良好的塑性性能,并且其摩擦性能高于其他两种材料,故可以取代其他两种材料成为风电制动片材料。Based on analyzing the wind turbine brake pad friction material, fiber reinforced composite materials is developed, and then by utilizing split Hopkinson pressure bar test equipment and MM-1000 adrasion test machine, the impact performare and wear resistance of brake pad friction materials are researched.Through comparing and analyzing the stress-strain and friction performance of the powder metallurgy copper, particulate reinforced composites and fiber reinforced composite material as well as fiber reinforced composite material,the fiber reinforced composite material with better impact resistance and good plastic properties is obtained,which friction properties are higher than the other two materials ,thus it can replace the other two materials as wind power brake materials.
