一、前言近十年来,复合材料有了很大发展,在宇航、航空和建筑等领域作为结构材料使用是屡见不鲜的。随着电子和电气工业的发展,往往需要材料具有优良的,可塑的介电特性及其它综合性能,而这通常是单一材料所不能提供的。由于某工程的需要,我们研 First, the foreword In the past ten years, the composite material has made great progress, and it is not uncommon to use it as a structural material in the fields of aerospace, aviation and construction. With the development of the electronics and electrical industries, it is often desirable for materials to have excellent, moldable dielectric properties and other comprehensive properties that are often not available with a single material. Due to the needs of a project, we research
