| 摘 要： | 采用硅橡胶热膨胀软模成型工艺制备高硅氧/酚醛防热材料,并用扫描电镜观察断面形貌,对比传统模压材料孔隙率和性能,对其密度及拉伸强度的离散系数进行分析。结果表明:软膜成型材料表面富有光泽;材料孔隙率低,接近"0";材料的密度和拉伸强度的离散系数分别为0. 09%和1. 95%,远小于传统模压成型材料相应的离散系数。

| Abstract: | High silica glass fiber/phenolic composites were prepared by thermal expansion molding (SRTEM) with silicone rubber.Morphology of the fracture surface was characterized by scanning electron microscopy.The porosity and performances between SRTEM and traditional molding composites were compared.The variation coefficients of density and tensile strength were analyzed.The results show that the SRTEM composites have higher surface gloss, and its porosity is low and close to 0.The variation coefficient of density is 0.09,and the variation coefficient of tensile strength is 1.95% and lower than that of traditional molding composites. |
