中文摘要：
选用0.13mm的W纤维编织成纤维毡,通过控制压制压力制备一系列孔隙度不同的W骨架,用高温熔渗得到Cu-W基复合材料。采用金相观察、物理和力学性能测试等试验手段,研究其显微组织、密度、硬度和电学性能。结果表明：用螺旋状W纤维织得的纤维毡,熔渗可得到较宽范围Cu含量的W纤维增强Cu基复合材料,W纤维均匀地分布在Cu基体内;W-Cu合金的相对密度达到98%以上,硬度超过86HB,电导率最高达到78.4%IACS。
英文摘要：
The W/Cu base composites were prepared by high temperature infiltration using 0.13mm tungsten fiber felt and tungsten skeletons with different porosity.The microstructure,density,hardness and electric properties of W/Cu composites were studied by metallographic observation,physical and mechanical tests.The experimental results indicate that the copper base composite materials can be obtained by high temperature sintering infiltration process with tungsten fiber being well-distributed in copper matrix.The relative density of the W/Cu composites is above 98%;hardness reaches more than 86HB,and conductivity rate reaches up to 78.4%IACS.
