复合材料的发展推动了增强用纤维材料向着多品种、高性能的方向迅速发展。碳化硅连续纤维是近年来日本首制成功的一种新型材料。由于β-SiC纤维具有高强、高弹性率,耐酸、耐氧化的性能好,比重小(～3.0),与金属浸润性好等多方面的优异特性,因此在许多领域具有很高的应用价值。一、原材料及材质的化学变化连续SiC纤维取材于有机原料,是通过化学变化转为无机材料的。在六十年代报导了:有机硅烷受热即易分解,Si-Si键(键能为50千卡/克分子)能向稳
The development of composites has promoted the rapid development of fiber materials for many varieties and high performance. Continuous silicon carbide is Japan’s first successful new type of material in recent years. Β-SiC fibers have high application value in many fields due to their excellent properties such as high strength, high elastic modulus, acid resistance, oxidation resistance, small specific gravity (~ 3.0) and good wettability with metals. First, the chemical changes of raw materials and materials Continuous SiC fibers drawn from organic materials, through chemical changes into inorganic materials. In the 1960s it was reported that organosilanes are readily decomposed by heat and that Si-Si bonds (bond energies of 50 kcal / mol)
