石英纤维是用高纯石英或天然水晶为原料制得的一种无机纤维，直径一般为几微米～几十微米。

它保持了固体石英的一些特点和性能，是一种优良的耐高温材料，可作为先进复合材料的一种增强相。石英玻璃纤维的SiO2质量分数高达99. 9%以上。耐高温性能比高硅氧纤维高，长期使用温度可达到1200℃ ，软化点温度高达1700℃ ，同时具有高的电绝缘性能，耐烧蚀，抗热震，优良的介电性能和良好的化学稳定性等。因此，石英纤维在军事、国防、航空、航天工业中有重要用途，可用于制造如火箭喷火口，航天热防护装置等。

Quartz fiber is an inorganic fiber made from high-purity quartz or natural crystal, and its diameter is generally a few micrometers to tens of micrometers.

It maintains some of the characteristics and performance of solid quartz, is an excellent high temperature resistant material, and can be used as a reinforcing phase of advanced composite materials. The SiO2 mass fraction of the quartz glass fiber is as high as 99.9% or more. The high temperature resistance performance is higher than that of the high silica fiber. The long-term use temperature can reach 1200℃, and the softening point temperature can reach 1700℃. At the same time, it has high electrical insulation properties, ablation resistance, thermal shock resistance, excellent dielectric properties and good chemistry. Stability and so on. Therefore, quartz fiber has important applications in the military, national defense, aviation, and aerospace industries, and can be used to manufacture rocket vents, aerospace thermal protection devices, and so on.
