提出了一种预测纤维颗粒增强复合材料力学性能的新方法--混合规则法。复合材料是通过一个假设的过程组成的，在这个过程中，用增强材料(纤维或颗粒)逐一增强基质。采用纤维增强材料的圆柱体模型和颗粒增强材料的球体模型，逐步得到复合材料的力学性能。将本方法得到的结果与其他方法和实验结果进行了比较。结果表明，对于纵向弹性模数，本方法与其他方法具有同样好的预测效果。对于横向模数和剪切模数，用本方法得到的结果与试验结果吻合较好。(C)1998由爱思唯尔科学有限公司出版。版权所有。
A new method of rule-of-mixture is presented for predicting the mechanical properties of fiber- and particle-reinforced composite materials. The composite material is composed through a hypothetical process in which the matrix is reinforced one-by-one with reinforcing materials (fibers or particles). The mechanical properties of the composed material are obtained step-by-step using the cylinder model for fiber-reinforced materials and the sphere model for particle-reinforced materials. Results obtained by the present method are compared with those of other methods and experimental results. It is found that, for the longitudinal modulus, the present method gives equally good prediction as other methods. For the transverse modulus and shear modulus, the results obtained by the present method show better agreement with experimental results. (C) 1998 Published by Elsevier Science Ltd.
