Description

一种混杂纤维夹层的天线罩
技术领域
本发明属于天线罩设计领域，具体涉及一种用于搜救通信设备的、混杂纤维夹层的天线罩。
背景技术
飞机遇险失事后，专业人员可以通过飞行技术参数和通信信息进行事故分析，以上信息通常由特定的航空搜救通信设备记录。为了在失事后便于寻找，搜救通信设备带有定位天线，调查人员用特定的接收机进行搜索，发现信号即可确定位置。搜救通信设备从飞机上抛射下来后，若坠落在陆地上，会产生极大的坠撞冲击载荷。因此，需采取相应的防护措施。
目前一般是在搜救通信设备的外部包裹金属防护层，但金属防护层不仅严重影响天线的定位功能，增加搜索难度，而且金属的刚度大，吸收的能量少，减振作用不明显，此外，金属的密度大，重量较重。
发明内容
本发明提出的混杂纤维夹层的天线罩，可以满足搜救通信设备高空抛射后的强度要求和电磁透波需要。
本发明的混杂纤维夹层的天线罩，天线罩为由内蒙皮、PMI泡沫芯层和外蒙皮组成的夹层结构，其中内蒙皮和外蒙皮都包含Kevlar纤维层和玻璃纤维层，两种纤维采用层间混杂的方式进行铺层。为了满足天线的定位功能，透波性能优良的玻璃纤维层是主体，为了满足强度要求，在内蒙皮的内层和外蒙皮的最外层是Kevlar纤维层，最内层为玻璃纤维层。为了减重、吸能和增强透波性能，在内、外蒙皮中间采用各向同性、密度低的PMI泡沫芯层，PMI是聚甲基丙烯酰亚胺。
本发明混杂纤维夹层的天线罩，可以解决搜救通信设备外部的防护罩强度和电性能矛盾的难题。不仅能够承受高达3500J的坠撞冲击载荷，吸收冲击能量，起到隔振和减振的作用，保护内部定位天线和搜救通信设备不损坏；并且具有良好的电磁透波性能，满足天线的定位功能，减低所搜难度。此外，主体是复合材料，重量较轻，能够有效减重。
本发明可在现有及以后多型天线罩的静力试验中使用。
附图说明
图1是本发明混杂纤维夹层的天线罩截面示意图。
具体实施方式
以下将结合附图对本发明天线罩的加工方法进行说明：
首先成型天线罩的内蒙皮，内蒙皮由Kevlar纤维层1和玻璃纤维层2按照层间混杂的形式进行铺层，铺层完成后在热压罐中固化成型；
在内蒙皮的玻璃纤维层2上放置加工好的PMI泡沫芯层3，整体在热压罐中固化成型；
在PMI泡沫芯层3的外表面铺设外蒙皮，外蒙皮由玻璃纤维层4和Kevlar纤维层5按照层间混杂的形式进行铺层，铺层完成后整体在热压罐中固化成型。
