Natural fiber–reinforced composites are increasingly being explored as sustainable alternatives to conventional metal and synthetic materials in automotive applications. Sisal fire (Agave sisalana) offers advantages such as low density, renewability, and good mechanical performance. This study evaluates the suitability of sisal fiber–reinforced composites for automotive bumper applications by examining key mechanical properties relevant to impact resistance and structural integrity. The results indicate that sisal fiber composites exhibit promising strength-to-weight characteristics and energy absorption capability, suggesting their potential as lightweight, cost-effective, and environmentally friendly materials for automotive bumper systems.
