Le résumé fourni par la source
To enhance the mechanical performance of single fibers and reduce the cost of carbon fiber composites, a hybrid fiber thin-walled tube structure with carbon/glass fiber alternating ply design was proposed. Experimental and numerical methods revealed the failure mechanisms and energy absorption properties of alternately layered carbon/glass fiber-reinforced tubes (C/GFRP tubes) under quasi-static compression. Results demonstrated significant improvements in energy absorption without increasing costs. The energy absorption mechanism mainly includes interlayer delamination of CFRP and GFRP, FRP fronds tearing and curling, and frictional dissipation between the tube and rigid plate. Compared to single-fiber structures, C/GFRP Tube exhibited a 23.16% improvement in specific energy absorption and a 20.99% improvement in crushing force efficiency. And a novel theoretical formula for the mean crushing force of hybrid fiber thin-walled tubes was established and verified, with an error of less than 8%. In addition, the influence of different structural parameters, ply angle configurations, and fiber hybrid ratios on energy absorption characteristics was systematically analyzed, providing a theoretical basis and design reference for the design of efficient and lightweight energy absorption devices.
