中文摘要：

采用犁切挤压及烧结的方法制造了沟槽铜纤维复合毛细芯铜板。复合毛细芯具有良好的传热性能，但应用时经常受压，为此研究其压缩性能非常必要。采用压缩试验对沟槽铜纤维复合毛细芯铜板进行实验研究，分析了铜纤维直径、孔隙率、烧结温度和烧结时间对沟槽铜纤维复合毛细芯铜板的压缩性能的影响。结果表明：纤维直径越大，最大应力越小；反之则越大。细纤维直径的铜纤维板获得的最大应力为6．9MPa，而中纤维直径的铜板的最大应力为6．2MPa，粗纤维直径的最大应力为5．7MPa。烧结温度越高，所获得的铜纤维板相应的应力值更大；烧结时间越长，所得的铜纤维板的相应应力值也越大；孔隙率越小应力值越大。对各种实验结果的原因进行了分析。

英文摘要：

A novel groove copper fibre composite wick copper board with good heat transfer performance was fabricated by plough-extrusion and sintering, but it is often compressed when applicating in heat transfer field, so the research on compression performance is very necessary. Compressive test was carried out to investigate the effects of porosity, copper fiber diameter and manufacturing parameters on the compressive properties of groove cop- per fiber composite wick copper board. During the compressive process, it was found that ： the larger fiber diame- ter, the smaller maximum stress. The maximum stress of copper fiber board with fine fiber diameter is 6. 9 MPa, and the maximum stress of medium fiber diameter is 6.2 MPa, the maximum stress of crude fiber diameter is 5.7 MPa. The higher sintering temperature, the larger corresponding stress, the longger sintering time, the larger corre- sponding stress value, the smaller porosity, the greater stress value. The reason of all experimental results is also analyzed.
