Abstract

This study aims to critically assess different micromechanical analysis models applied to carbon-fiber-reinforced plastic (CFRP) composites, employing micromechanics-based homogenization to accurately predict their effective properties. The paper begins with the simplest Voigt and Reuss models and progresses to more sophisticated micromechanics-based models, including the Mori-Tanaka and Method of Cells (MOC) models. It provides a critical review of the areas in which these micromechanics-based models are effective and analyses of their limitations. The numerical analysis results were confirmed through finite element simulations of the periodic representative volume element (RVE). Furthermore, the effective properties predicted by these micromechanics-based models were validated via experiments conducted on IM7/5320-1 composite material with a fiber volume fraction of 0.62.

摘要

本研究旨在严格评估应用于碳纤维增强塑料（CFRP）复合材料的不同微观力学分析模型，采用基于微观力学的均匀化方法来准确预测其有效性能。本文从最简单的Voigt和Reuss模型开始，进而探讨更复杂的基于微观力学的模型，包括Mori-Tanaka模型和元胞法（MOC）模型。它对这些基于微观力学的模型有效的领域进行了批判性综述，并分析了它们的局限性。数值分析结果通过周期性代表性体积单元（RVE）的有限元模拟得到了证实。此外，这些基于微观力学的模型所预测的有效性能通过在纤维体积分数为0.62的IM7/5320-1复合材料上进行的实验得到了验证。
