摘要
研究了短切碳纤维、碳化硅晶须、硼酸铝晶须为增强体的镁基复合材料在外加载荷下的阻尼性能,测量了它们的力学性能与断口特性。研究表明:增强体不同的镁基复合材料,阻尼性能不同;在所研究的几种增强体复合材料中,以短切碳纤维增强镁基复合材料的阻尼效果最好;短切碳纤维增强铁基复合材料界面对内耗有明显的影响。
This paper deals with the damping characterstics of short carbon fiber、SiC whisker and 2B2O3. Al2O3 whisker reinforced magnesium composites, analyses their mechanical properties and fracture surfaces. Damping behavior of magnesium composites vary as reinforcers. C(f) /Mg composites exhibit higher damping than whiskers reinforced magnesium composites. Fiber/matrix interface plays an important role in damping.
