Quartz fiber needling preform is a three-dimensional fabric with an overall structure composed of quartz fiber mesh felt, quartz fiber cloth or quartz fiber in an directional or non-directional combination. Quartz fiber refers to a special glass fiber with a silica content of more than 99.90% and a wire diameter of 1~15μm. It has high heat resistance and can be used at 1050 °C for a long time, and the instantaneous resistance is as high as 1700 °C. At the same time, the dielectric properties of the quartz fiber are also very good, which can realize the characteristics of broadband wave transmission.
