Preparation method of quartz fiber reinforced silicon dioxide antenna housing
The invention discloses a preparation method of a quartz fiber reinforced silicon dioxide antenna housing, and belongs to the technical field of fiber reinforced composite materials. The method comprises the following steps: soaking a fabric preform with a supporting mold in an organic solvent to remove an impregnating compound; then placing in a mold, carrying out silicon dioxide sol vacuum impregnation, drying, removing the shaped prefabricated body from the supporting mold, and then carrying out drying and high-temperature heat treatment to obtain a cover body blank; and placing the cover body blank in a mold, carrying out silicon dioxide sol vacuum impregnation, taking out, rotating by using a rotating tool, feeding into a drying oven, carrying out drying and high-temperature heat treatment, repeating for multiple times, and carrying out mechanical finish machining to obtain the quartz fiber reinforced silicon dioxide antenna cover. According to the method, the silicon dioxide sol does not need to be concentrated, the sol can be repeatedly used without being subjected to a gelation process, and the prepared antenna housing is excellent in uniformity.
本发明公开了一种石英纤维增强二氧化硅天线罩的制备方法，属于纤维增强复合材料技术领域。本方法通过将带有支撑模的织物预制体在有机溶剂中浸泡来去除浸润剂；然后放置于模具中，进行二氧化硅溶胶真空浸渍，干燥后将定形后预制体从支撑模上脱出，然后经过干燥和高温热处理得到罩体毛坯；在将罩体毛坯放置于模具中，进行二氧化硅溶胶真空浸渍取出后用旋转工装进行旋转，再送入烘箱中进行干燥和高温热处理，重复多次后进行机械精加工，得到石英纤维增强二氧化硅天线罩。本方法无需对二氧化硅溶胶进行浓缩处理，溶胶无需经历凝胶过程可重复使用，制备的天线罩的均匀性优良。
