2DCf/Mg-2.0Re-0.2Zr复合材料的尺寸稳定性
, PP. 119-123
Keywords: 碳纤维织物/Mg-2.0Re-0.2Zr合金复合材料,热膨胀,尺寸稳定性
Abstract:
采用压力浸渗法制备碳纤维织物(2DCf)及单向碳纤维(1DCf)增强镁合金复合材料,测试了两种复合材料在50---350℃范围内的热膨胀行为.结果表明,2DCf/镁合金复合材料(简称2D)平面内不同方向的平均热膨胀系数均随温度升高不断降低.从50到350℃,0°/90°方向的平均热膨胀系数由4.03×10-6℃-1降至1.83×10-6℃-1;45°方向的平均热膨胀系数由4.53×10-6℃-1降至2.31×10-6℃-1.根据推导公式可以准确计算2D增强复合材料20---150℃范围内0°/90°方向的平均热膨胀系数.20---150℃热循环测试结果表明,2D复合材料具有较好的尺寸稳定性,在热循环过程中存在应变滞后现象,其残余塑性变形主要是基体合金在热应力作用下产生的塑性变形,并且从第2次热循环起,复合材料在热循环中产生的净应变不随热循环次数增加而变化.
