复合材料是材料科学的发展方向之一,大致有纤维强化、分散强化和复层强化三种。由于复合材料兼具单一材料所不具备的综合性能,而作为复层强化的复合材料,通过具有不同性质材料的组合,可以克服仅仅单一材料时所具有的弱点或者通过组合可以 Composite materials is one of the development direction of material science, there are about three kinds of fiber strengthening, dispersion strengthening and multi-layer strengthening. Due to the composite material not having the combined properties of a single material, as a composite material with multiple layers, the combination of materials with different properties can overcome the weaknesses of only a single material or by combining
