摘要: 对聚四氟乙烯(PTFE) 和玻纤增强PTFE 进行了差热分析, 确定了玻纤增强PTFE 的基 本工艺参数, 根据对高速宽频带防空导弹天线罩蒙皮的性能要求, 考察玻纤增强PTFE 拉伸强度 和介电性能。结果表明: 11% 短玻纤和37% 玻纤布(重量百分含量) 增强PTFE 具有最高的拉伸强 度和良好的介电性能。由于某种粒子的加入, 在扫描电镜下很容易观察到PTFE 的结晶现象。Abstract: Heat analysis of PTFE resin and glass reinforced PTFE was completed and the basic manufacturing process parameters were assured. In terms of the requirements of characteristics of highspeed broadband missile radome outlayer, the tensile strength and dielectric properties were investigated. The results showed that about 11% (weight fabrication) chopped fiber or 37% glass cloth reinforcing PTFE had the highest tensile strength and acceptable dielectric properties. Crystallizing phenomenon of PTFE was discovered easily with the adding of some particles. Finally, prediction of dielectric properties was discussed.
