1. Improve strength and stiffness: The strength and elastic modulus of quartz fiber are much higher than those of ordinary glass fiber, which can effectively improve the mechanical properties of composite materials, making them more robust and durable.
2. Weight reduction: Quartz fiber has a low density, which can reduce the weight of composite materials while ensuring strength. This is particularly important for weight sensitive fields such as aerospace and automotive.
3. Excellent high temperature resistance: The softening point of quartz fiber is as high as 1700 ℃, and the long-term using temperature can reach 1050 ℃, which can significantly improve the high temperature resistance of composite materials and maintain stability in high temperature environments.
4. Good corrosion resistance: Quartz fiber is corrosion-resistant and hardly reacts with other acids except hydrofluoric acid and hot phosphoric acid, which can improve the service life of composite materials in harsh environments.
5. Low dielectric constant and loss: Quartz fiber has excellent dielectric properties, exhibiting extremely low dielectric constant and dielectric loss at high and ultra-high frequencies, making it an ideal choice for manufacturing high-performance transparent materials.
Based on the performance introduced above, quartz fiber has been widely used in multiple fields. Shenjiu Quartz Fiber independently develops and produces quartz fiber yarn, quartz fiber cloth, etc., which have shown great potential in the fields of civilian ultra-high temperature and aerospace.
