摘要

采用一种简化的微力学方法对单向复合材料性能进行建模和分析。本文研究了体积分数和组分性质对单向复合材料有效纵向、横向和剪切性能的影响。这些有效的性能是使用微观力学方法确定的，这是基于使用混合规则的数学建模。采用T300/BSL914C、IM7/8511-7、T300/PR319和S2-Glass/epoxy四种不同类型的单向复合材料进行分析。用已有的实验结果对该方法进行了验证。响应取决于一系列参数，如纤维的取向、纤维的体积分数、纤维阵列及其组分的材料特性。此外，这种微力学方法还可以与其他增强纤维一起用于UD、混杂纤维和其他复合材料结构的性能预测。

Simplified micromechanics approach to analysis the performance of UD composites

A simplified micromechanical approach is used for the modelling and analysis of unidirectional (UD) composite performance. In this paper, the influence of volume fraction and constituent properties on the effective longitudinal, transverse, and shear properties of unidirectional composites are investigated. These effective properties are determined using the micromechanical approach, which is based on mathematical modelling using the rule of mixtures. Four different types of unidirectional composites such as T300/BSL914C, IM7/8511-7, T300/PR319, and S2-Glass/epoxy were used for analysis purposes. The method was validated with existing experimental results. The response is dependent on an array of parameters, such as the orientation of fibers, the volume fractions of fibers, array of fibers and the material properties of their constituents. Further, this micromechanical method might be used with other reinforcing fibers for the prediction of properties of UD, hybrid and other composites architectures.
