Quartz fiber needle punched preform is a three-dimensional fabric with an overall structure of quartz fiber mesh felt, quartz fiber cloth or quartz fiber combined in a directional or non-directional manner. Quartz fiber refers to a special glass fiber with a silicon dioxide content of more than 99.90% and a wire diameter of 1`15μm. It has high heat resistance and can be used at 1050℃ for a long time and can withstand up to 1700℃ instantly. At the same time, the dielectric properties of quartz fiber are also very excellent, which can achieve the characteristics of broadband wave transmission.

Application areas:

• Aerospace
• Military industry
• Semiconductors
• High temperature insulation
