Type: article
Abstract: Analytical models for predicting the mechanical properties of composite materials are useful when experimental procedures are not feasible. This study presents a review of micromechanical analytical models used to predict the Young’s modulus of fiber-reinforced composites (FRC). The theoretical models assessed in this work include the series and parallel models, the effective modulus approach, the Halpin-Tsai equations, and the Cox and Nilsen models, due to their relatively simple mathematical descriptions. The study focused on an epoxy matrix reinforced with carbon fiber, E-glass, and Kenaf (a natural fiber), as these fillers are commonly used in various industrial and research applications. The comparison between experimental and predicted values indicates that models such as the Halpin-Tsai and effective modulus approach provide better agreement with the experimental measurements for the targeted composites.
