|
Abstract:
在对含乙烯基聚硅氮烷（PSN1）树脂基本性能研究的基础上，以石英纤维布为增强材料，利用层压法制备了石英纤维布/含乙烯基聚硅氮烷耐高温透波复合材料（QF/PSN1），并对其在室温和高温下的力学性能及介电性能进行了测试与表征。研究结果表明：PSN1树脂工艺性能良好，黏度低于1 Pas（60~151℃），固化温度小于200℃；耐热性能优异，在N2和空气氛围下，其固化物失重5%时的温度均高于480℃、800℃时的残重均高于76%。QF/PSN1复合材料力学性能优异，弯曲强度和层间剪切强度随温度升高出现先下降后上升的趋势；450℃烘烤10 min后，其弯曲强度仍在120 MPa以上。QF/PSN1复合材料介电性能优异：在1~12 GHz范围内，QF/PSN1复合材料在室温~450℃范围内介电常数（ε）均低于3.2，介电损耗（tanδ）均小于0.01。上述研究结果表明：含乙烯基聚硅氮烷作为耐高温透波材料的新型树脂基体具有重要的应用价值。 Based on the study of the basic properties of vinyl-containing polysilazane (PSN1) resin, a polysilazane-based high-temperature wave-penetrating composite quartz fiber/PSN1(QF/PSN1) was fabricated by laminated pressing method using quartz fiber cloth as the reinforcing material. The mechanical properties and dielectric properties of the QF/PSN1 composites at room and high temperature were investigated. The results show that PSN1 resin has excellent processing ability with viscosity lower than 1 Pas between 60℃ and 151℃, and low curing temperature less than 200℃. The cured PSN1 resin exhibits high thermal stability T5% (the temperature at which the mass of the resin lost 5%) above 480℃ and WR (the mass residual fraction) above 76% at 800℃ in both N2 and air atmosphere. The flexural strength and interlaminate shear strength (ILSS) of QF/PSN1 composites show a trend of decreasing first and then increasing with the rising of temperature. And the flexural strength is more than 120 MPa after holding for 10 min at 450℃, which demonstrates that the QF/PSN1 composites possess excellent mechanical properties. QF/PSN1 composites show superior dielectric properties with dielectric constant (ε) lower than 3.2 and dielectric loss (tanδ) all less than 0.01 from room temperature to 450℃ in the frequency range of 1~12 GHz. The above studies indicate that PSN1 resin has high potentials as a new type of resin matrix for the high-temperature wave-penetrating composites
