引言选择二种以上不同性能的纤维混杂在一起,发挥各自的长处,使结构设计的自由度增加、做到产品安全、经济,是目前复合材料应用方面有兴趣的课题。我们把二种以上增强纤维增强同一基体的复合材料称之为混杂复合材料。混杂复合材料不仅扩大了复合材料的使用范围,而且可以降低成本,取得明显的经济效益。通过调整组份纤维的含量和“混杂效应”,可获得良好的材料性能。例如:碳纤维具有高强、高模、低密度等优点,但存在脆性,断裂延伸率小,相对价格
Introduction Choose more than two kinds of different performance of the fiber mixed together to play their own strengths, so that the freedom of structural design increase, so that the product is safe and economical, is the current application of composite materials are interested in the subject. We refer to composite materials in which more than two types of reinforcing fibers reinforce the same matrix as hybrid composites. Hybrid composite materials not only expand the scope of the use of composite materials, but also reduce costs and achieve significant economic benefits. By adjusting the content of the component fibers and the “confounding effect”, good material properties can be obtained. For example: carbon fiber with high strength, high modulus, low density, etc., but there is brittleness, elongation at break, the relative price
