摘要
Abstract
In view of a high temperature resistant radome setting special demands on root strength and matching of coefficient of thermal expansion between root material and metal connector,several kinds of quartz fiber fabric with needled structures for radome are designed,alumina fibers are introduced into the root of the needle punching fabric,and the properties of the composite materials at the root of the radome are studied systematically.The results show that the proper reduction of the content of felt in needle punc-hing fabric can improve the tensile strength in the composite material but the inter-laminar shear strength and compressive strength of the composite can also be partly reduced.Although the coefficient of thermal expansion of the composite material at the root of radome can be improved by introducing the alumina fiber into the root of radome obviously,the tensile strength of the composite material at high temperature show a kind of U-shaped trend with the increasing content of alumina fibers,i.e.descending in advance and climbing behind.The research of the relevant technology provides a reference for the design of high tem-perature resistant radome.关键词
