Ceramic radome composite material and forming method thereof
The invention discloses a forming method of a ceramic radome composite material, which comprises the following steps of: 1) preparing a basalt fiber prefabricated part: weaving satin cloth by adopting continuous basalt fibers, and making two layers of satin cloth, a basalt fiber grid fixing layer and a basalt fiber web body into a unit layer for laying, performing layer-by-layer needling to form an integral fabric, and performing penetration sewing by adopting a sewing line to form a basalt needling prefabricated member; (2) dipping and forming; 3) sintering at low temperature; and 4) repeating the steps 2) and 3) twice to form the ceramic radome composite material. The invention also discloses the ceramic radome composite material formed by the method. The basalt fiber preform material disclosed by the invention is impregnated and sintered by silica sol, so that the obtained material not only has relatively good wave-transparent performance, but also has relatively high temperature tolerance and relatively good mechanical, electrical and thermal properties, can replace a resin-based wave-transparent material, and overcomes the defect that the resin-based wave-transparent material cannot be used for a long time in a medium-temperature environment.
本发明公开了一种陶瓷天线罩复合材料的成型方法，该方法包括如下步骤：1)制备玄武岩纤维预制件：采用连续玄武岩纤维编织缎纹布，将两层缎纹布、一层玄武岩纤维网格固定层和一层玄武岩纤维网胎制定为一个单元层进行铺层，再逐层针刺形成整体织物，然后采用缝合线贯穿缝合，形成玄武岩针刺预制件；2)浸渍成型；3)低温烧结；4)重复步骤2)和3)两次，形成陶瓷天线罩复合材料。本发明还公开了上述方法成型的陶瓷天线罩复合材料。本发明的玄武岩纤维预制件材料经过的硅溶胶的浸渍、烧结，得到材料不仅具有较好的透波性能，还具有较高的耐受温度，较好的力学、电学和热学性能，可替代树脂基透波材料，克服了树脂基透波材料中温环境下不能长期使用的缺点。
