摘要

This research focuses on the comprehensive characterization and evaluation of carbon fibre reinforced polymer (CFRP) composite laminates with diverse stacking sequences, specifically under low-velocity impact. The investigation applies Charpy impact and three-point bending tests to analyze the impact response and flexural behaviour. The study goes through the influence of stacking sequences on mechanical properties, including Young’s modulus. The analysis validates experimental data and finite element analysis simulations for verification. Design 1 (using conventional stacking sequence) exhibits the highest ultimate tensile strength and brittleness, while design 2 (using alternating stacking sequence) presents intermediate strength. Design 3 (using an even stacking sequence) demonstrates unique behaviour with a “spring-like” quality. The research emphasizes the role of stacking sequences in CFRP behaviour, offering insights for car chassis applications. It acknowledges the limitations of measurement precision and underscores the importance of validating simulation results with experimental data. Integrating simulation tools like Abaqus proves crucial in optimizing CFRP product design and performance while maintaining alignment with real-world behaviour.
