含有两种或两种以上纤维的复合材料称为混杂复合材料。混杂复合材料之所以具有吸引力，是因为材料的剪裁比非混杂复合材料更容易，目前广泛应用于飞机、体育用品等领域。本文首先回顾了包括混杂复合材料在内的复合材料细观力学强度的研究工作。其次，利用剪切滞后假设计算了断裂纤维周围的应力集中，这是统计强度理论所必需的。在本文的最后部分，通过蒙特卡罗模拟进行了强度预测。
Composite materials containing two or more types of fibers in a common matrix are called hybrid composites. Hybrid composites are attractive because tailoring of materials is easier than non-hybrid composites, and they are now widely used including aircraft, sports goods, and so on. This paper first reviews the research works on micromechanical strength of composites including hybrid composites. Next, stress concentration around broken fibers is calculated by means of a shear-lag assumption, which is necessary for a statistical strength theory. In the last part of this paper, a strength prediction is made by the Monte Carlo simulation.
