Quartz glass fiber, also known as Q-glass fiber, is a special glass fiber with a long-term use temperature of up to 1050 degrees and a dielectric constant as low as 3.78. Quartz glass fiber has high temperature resistance, excellent dielectric properties, high strength and high modulus. Quartz fibers are mostly used in the fields of high wave transmission, high temperature resistance, heat insulation, and ablation resistance in the aerospace field, and meanwhile some applications in civil high-performance radomes

　　and industrial high-temperature fields.
