Electromagnetic Wave Penetrating Functional Composite Materials Through The Waves Cover The Development,

The technology for making composite wave penetrating lid is discussed in this paper which is composed of the following four parts: the material design, the structure design , the technology design and its function tests.The material design is based on the electronic property, heat resistance property , easy molding property and the newly development state of high quality polymers. The strength and electronic properties of the reinforce are emphasized when it is chosen. All those work is verified by material tests. The structure of the lid is designed according to the wave penetrating theory and is optimized by using finite element method. RTM is improved when it is used under the condition of making this chick productions. Function tests emphasize on testing of the general property of the lid and are composed of two parts which are wave penetrating test and displacement resistance test.
