Fine-braided thin-layer SiO2f/SiO2 antenna window and preparation method thereof
The invention relates to a fine-braided thin-layer SiO2f/SiO2 antenna window and a preparation method thereof, belongs to the technical field of fiber reinforced composite material antenna windows, and solves the problems of large wall thickness, low strength and low production efficiency of a SiO2f/SiO2 composite material for preparing an antenna window in the prior art. The invention relates to a quartz fiber preform for preparing an antenna window, the quartz fiber preform is formed by weaving warp yarns and weft yarns and is a fine-woven thin-layer SiO2f/SiO2 fiber fabric with a 2.5 D structure, and all the warp yarns sequentially penetrate through two adjacent columns and two adjacent rows of weft yarns along the diagonal direction; the warp density of the warp is 11-13 pieces/cm, the weft density of the weft is 8-10 pieces/cm, and the layer density is 25-35 layers/cm. The preparation of the thin-wall SiO2f/SiO2 composite material antenna window with excellent mechanical property, uniform electrical property and good heat resistance is realized.
本发明涉及一种细编薄层SiO2f/SiO2天线窗及其制备方法，属于纤维增强复合材料天线窗技术领域，解决了现有技术中用于制备天线窗的SiO2f/SiO2复合材料壁厚较大、强度不高以及生产效率低的问题。一种用于制备天线窗的石英纤维预制体，所述石英纤维预制体由经纱和纬纱编织而成，为2.5D结构的细编薄层SiO2f/SiO2纤维织物，所有经纱沿对角方向依次穿过相邻的两列和两行纬纱；所述经纱的经密为11‑13根/cm，所述纬纱的纬密为8‑10根/cm，层密度为25‑35层/cm。实现了力学性能优异、电性能均匀、耐热性能良好的薄壁SiO2f/SiO2复合材料天线窗的制备。
