| 摘 要： | 采用CaCO3作为发泡剂用熔体发泡法制备泡沫SiC/ZL104复合材料，用CMT5205电子万能试验机对该材料压缩性能进行测试，并分析泡沫SiCn/ZL104复合材料在外力作用下的破坏机理及SiC颗粒粒径和相对密度对该材料压缩性能的影响规律。研究结果表明：泡沫SiCp/ZL104复合材料受轴向压缩时由于孔壁发生弯曲和横向拉伸而呈脆性逐层破坏或沿斜截面断裂的特征；当SiC颗粒粒径由28 μm减小到5 μm时，泡沫5％SiCp/ZL104(体积分数)复合材料的屈服应力由5 MPa增至11MPa;当其相对密度由0.16增至0.32时，对应的屈服应力由5 MPa增至10MPa。 |
