Experimental investigation of multiple stress creep-recovery behavior in hybrid carbon/agave woven composites

This study investigates the multiple stress creep-recovery behavior of hybrid carbon/Agave woven composites. Agave fibers were extracted using mechanical, chemical, and biological methods, with tensile tests identifying the chemical treatment (3H NaOH) as slightly superior. Five woven configurations were fabricated: Taffeta weaves of carbon (CTT) and Agave (ATT), hybrid carbon-Agave (HCA), hybrid Agave-carbon (HAC), and hybrid mixed (HMT) weaves with alternating fibers. Tensile tests were conducted at speeds of 0.1, 1, and 10 mm/s. Results show that testing speed significantly affects mechanical response. ATT exhibited the highest deformation, indicating compliance, while HMT showed the lowest strain, reflecting stiffness. HCA and HAC displayed intermediate behaviors, balancing flexibility and strength. These findings suggest ATT is suitable for energy-absorbing applications such as damping or cushioning, whereas HMT is better suited for load bearing or fatigue-critical components. The study highlights the potential of tailoring hybrid woven composites’ mechanical properties through fiber selection, arrangement, and testing conditions.
