Crashworthiness analysis and morphology of hybrid hollow tubes reinforced by aluminum mesh with hybrid woven fibre composites (basalt, jute, hemp, banana, bamboo) using roll-wrapping technique

This study investigated the mechanical performance of hybrid tubes made via roll-wrapping and enhanced with an aluminum mesh and epoxy matrix (AL-DMEM). The specimens included Basalt + Jute (BJAJB), Basalt + Bamboo (BBmABmB), Basalt + Banana (BBaABaB), Basalt + Hemp (BHAHB), and Basalt (BAB). The BBmABmB specimen showed the best mechanical properties with the highest peak crushing force, specific energy absorption, mean crushing force, and total energy absorption. The AL-DMEM integration improved load-bearing capacity and energy absorption, reducing matrix cracking and fiber breakage. Scanning electron microscopy and energy-dispersive X-ray analysis highlighted BBmABmB’s robust reinforcement. Its superior structural integrity and aluminum content make it suitable for applications requiring high structural integrity, such as micromobility vehicles, highlighting the potential of AL-DMEM-reinforced composites in advanced engineering applications.
