液态复合材料成型（LCM）过程中产生的孔隙对LCM复合材料的力学性能产生不利影响。作者团队最近开发了一种预测孔隙复合材料弹性性能的微观力学模型。在这项研究中，提出了一个独特的实验程序来验证这个分析模型。分析模型用于评估微孔隙对纤维束增强复合材料弹性性能的影响。最后，建立了空心LCM复合材料的有限元模型，并与解析模型预测结果进行了比较。

Voids induced by liquid composite molding (LCM) process adversely affect the mechanical properties of the LCM composites. A micro-mechanics model to predict the elastic properties of voided composites has been recently developed by the author's group. In this study, a unique experimental procedure is presented to verify this analytical model. The analytical model is used to evaluate the micro void effect on the elastic properties of fiber tow reinforced composites. Finally, an FEM modeling of voided LCM composites is developed and compared with the analytical model prediction results.
