Analytical Modeling of Mechanical Tensile Characteristics of Polyamide Composites Reinforced with Glass Fibers

This chapter delves into the analytical modeling of mechanical tensile characteristics for polyamide composites reinforced with glass fibers. It explores the use of various mathematical models, including the Rule of Mixture, Inverse Rule of Mixture, Halpin-Tsai, and Hirsch models, to predict tensile properties such as Young’s modulus, tensile strength, and elongation. The study compares these predicted results with experimental measurements, highlighting the accuracy and limitations of each model. The research also investigates the influence of fiber content and orientation on the mechanical properties of the composites. Key findings include the strong correlation between the Rule of Mixture model and experimental results at lower fiber content, while higher fiber content shows significant deviations due to fiber reorientation during compression molding. The chapter concludes with a discussion on the value of analytical models in predicting composite behavior and suggests future work involving numerical simulations to better understand the material's response to various loading scenarios.
