Nitride fiber reinforced nitride ceramic antenna housing and preparation method thereof
The invention provides a nitride fiber reinforced nitride ceramic antenna housing and a preparation method thereof. The preparation method comprises the following steps: S1, weaving a nitride fiber antenna housing preform; s2, depositing a boron nitride interface coating on the nitride fiber radome preform to obtain an intermediate; s3, the intermediate is placed in a limiting mold tool provided with a plurality of through holes, a dipping mold tool is arranged outside the limiting mold tool, a nitride ceramic precursor is injected between the limiting mold tool and the dipping mold tool, dipping forming and cracking are repeated, and an antenna housing blank is obtained; and S4, carrying out ceramization on the radome green body to obtain the nitride fiber reinforced nitride ceramic radome. According to the preparation method, after the coating is prepared on the prefabricated body, compounding of the nitride ceramic precursor and the prefabricated body is completed based on the limiting mold tool and the dipping mold tool which are provided with the multiple through holes, deformation is not prone to occurring in the dipping forming and cracking process, demolding is easy, the precursor consumption is saved, the cost is low, and the antenna housing is good in comprehensive performance.
本发明提供一种氮化物纤维增强氮化物陶瓷天线罩及其制备方法，包括以下步骤：S1、编织氮化物纤维天线罩预制体；S2、在氮化物纤维天线罩预制体上沉积氮化硼界面涂层，得到中间体；S3、将中间体置于设有若干通孔的限位模具工装中，在限位模具工装外设置浸渍模具工装，向限位模具工装和浸渍模具工装之间注入氮化物陶瓷前驱体，重复浸渍成型和裂解，得到天线罩坯体；S4、将天线罩坯体进行陶瓷化，得到氮化物纤维增强氮化物陶瓷天线罩。本发明制备方法在预制体上制备涂层后基于设有若干通孔的限位模具工装和浸渍模具工装完成氮化物陶瓷前驱体与预制体的复合，浸渍成型和裂解过程不易变形，易脱模，节省前驱体用量，成本低，天线罩综合性能好。
