复合材料性能优异、应用广泛、种类繁多、还会有新的发展。复合材料的定义尚未统一,这里指纤维增强塑料(FRP)。 从宏观看,复合材料是各向异性的层合材料。从细观看,复合材料是纤维和基体组成的多相非均质材料。一般认为纤维起主要的承力作用,而基体起保护纤维和传力作用,然而情况并非如此简单。 多数复合材料结构的工程问题,用复合材料宏观力学就能得到基本解决。在对复合 Composites excellent performance, wide range of applications, a wide range, there will be new developments. The definition of composite materials has not been unified, here refers to fiber reinforced plastic (FRP). From a macroscopic perspective, composite materials are anisotropic laminates. From a microscopic point of view, the composite material is a heterogeneous heterogeneous material composed of fibers and matrix. Generally believed that the fiber plays a major role in the load-bearing, and the substrate to protect the fiber and force transmission, but the situation is not so simple. The engineering problems of most composite structures can be basically solved by macro mechanics of composite materials. In the compound
