摘　　要：硅橡胶材料是一种优良的模具材料,它不仅具有优异的仿真性、脱模性,而且收缩率低、加工成型方便、耐热老化性能较好,同时硅橡胶还具有在很宽的温度范围内长时间保持弹性的特点,这使得其作为热膨胀模在聚合物基复合材料成型中得到了广泛应用。综合介绍了硅橡胶在聚合物基复合材料成型中的应用,系统阐述其在成型工艺中的应用研究现状,并展望了其今后的发展方向。Silicon rubber is an excellent mold material which has significant characteristic including simulation, demoldation, low shrinkage, easy fabrication, and aging-resistant, especially the material can keep elasticity for a long time at a wide range of temperature. All these characteristics make it widely used for heat-expansion mold in polymer based composites molding. In this paper, the application of silicon rubber in polymer based composites fabrication is introduced in detail based on the latest research result of domestic and foreign. The recent research achievements are reviewed and the development prospects are outlined.
