Multiscale Dispersity Analysis and Fatigue Life Prediction of Fiber-Reinforced Composites

Abstract:

Fiber-reinforced composites are widely used in lightweight design for their exceptional specific strength. However, their inherent multiscale property variations require systematic consideration during structural optimization. This study develops a cross-scale analysis framework and fatigue life prediction model that explicitly accounts for the propagation of mechanical property variations from microscale constituent properties to macroscopic performance, utilizing representative volume element (RVE) modeling. Application of the framework to a carbon fiber composite battery box verifies its predictive capability, with results quantitatively revealing the mechanisms by which property variations affect structural durability. These findings establish a fundamental methodology for evaluating the operational performance of automotive composite structures.
