On lateral crashworthiness and failure mechanisms of multi-fibers hybrid composite corrugated structures with carbon, glass, Kevlar
Highlights The lateral crushing of multi-fiber HFRP corrugated laminates with different stacking sequence, fiber type, and fiber dispersibility are studied. Hybridization of carbon, and Kevlar fiber contributes greatly to failure modes and energy-absorption. A comprehensive evaluation is conducted on the property and cost of multi-fiber HFRP corrugated laminates. Revealing failure mechanisms and hybridization effects of multi-fiber HFRP corrugated laminates under lateral loading.
Abstract Fiber hybridization can effectively modulate and control the failure modes of composite structures, thereby altering the mechanical properties. However, the understanding of complex hybrid effects remains insufficient restricting the practical utilization. This study focuses on hybrid composite corrugated structures with carbon, glass, and Kevlar fibers through the lateral crushing experiments on single-fiber corrugated laminates, double-fiber hybridized corrugated laminates, and triple-fiber hybridized corrugated laminates, the crashworthiness, failure mechanism, and hybrid effects are revealed in detail. The experimental results show that (KF3\CF3)S and (CF3\GF3)S exhibit excellent comprehensive performance including SEA and SEA/cost. The high dispersion exhibits negative hybrid effects. Kevlar fiber can effectively inhibit crack propagation and maintain the overall structural integrity. This study has deepened an understanding of the failure mechanisms and hybridization effects of hybrid composite corrugated structures subjected to lateral compressive load, providing guidance for the hybrid design of composite structures.
