| 摘 要： | 采用热压工艺制得聚四氟乙烯/陶瓷/玻璃纤维复合介质材料。复合介质材料的介电常数随着PTFE和玻璃纤维含量的增加而减小;当复合介质中不含玻璃纤维时,随着陶瓷粉料的质量分数从40%增加到65%时,材料的弹性模量先减小后增加;加入玻璃纤维可以增加材料的弹性模量,对于PTFE的质量分数为40%的复合介质,玻璃纤维加入的质量分数不应大于15%,聚四氟乙烯/陶瓷/玻璃纤维复合介质的微观结构致密、形成了完整的一体。

| Abstract: | The composite dielectrics mainly composed of PTFE, ceramics and glassfibers are prepared by hot pressing.Dielectric constant of the composites decreases with amount of PTFE and glassfibers increasing. For PTFE/ceramics composites, the elastic modulus increases at first and then decreases with the amount of ceramics increasing from 40% to 65%. The addition of glassfibers in PTFE/ceramics can increase elastic modulus. And for composite dielectrics containing 40% PTFE, the amount of glassfibers should be less than 15%. The composites microstructures are very dense |
