The mechanical properties of a hybrid structure consisting of a glass–epoxy composite and a perforated metal sheet were evaluated. The composite, hybrid, and resins were produced and their tensile behaviors were measured. Finite-element (FE) modeling was then used to predict the material's properties, based on the constituent properties, and also to analyze the stress distribution in each material. A new micromechanical model was developed to predict the hybrid's modulus and strength at different stages of deformation. Both the FE and micromechanical modeling accurately predicted these properties. It was also found that perforating the metal layer of a composite-metal hybrid can increase the specific strength of the material.

玻璃纤维增​​强复合材料/多孔金属薄板杂化物的机械性能

对由玻璃-环氧树脂复合材料和穿孔金属板组成的混合结构的机械性能进行了评估。生产了复合材料，杂化材料和树脂，并测量了它们的拉伸性能。然后使用有限元（FE）建模基于组成特性来预测材料的特性，并分析每种材料中的应力分布。开发了一种新的微机械模型来预测混合体在不同变形阶段的模量和强度。有限元模型和微机械模型均能准确预测这些特性。还发现在复合金属混合材料的金属层上打孔可以增加材料的比强度。
