摘　　要：基于钢纤维聚合物混凝土(SFPC)在机床基础件中的应用,分析影响SFPC热变形的因素,对SFPC热态性能参数——热变形系数进行测试,在此基础上对SFPC机床基础件与传统铸铁机床基础件的热性能进行分析比较.结果表明SFPC机床基础件优于传统铸铁机床基础件,证明用钢纤维聚合物混凝土制造机床基础件可使机床具有更好的热稳定性,从而满足科技发展对机床高加工精度的要求.In order to use the steel-fiber polymer concrete（SFPC） in machine tool structural elements, the factors influencing on thermal properties of steel-fibre polymer concrete were analyzed and the thermal distortion coefficient of the SFPC as its thermal characteristic parameter was tested. The thermal properties of machine tool structural element with SFPC were compared to those with conventional cast iron. The result showed that the former was superior to the latter, so that it was verified that a better thermal stability of machine tool structural elements could be achieved by using steel-fibre polymer concrete and high machining accuracy required by the technical development would be realized thereby.
