This document presents an experimental study on the mechanical and dynamic characteristics of hybrid natural fiber composites made from banana and sisal fibers reinforced with epoxy resin. Samples were prepared with different volume fractions of banana and sisal fibers and tested using an FFT analyzer to determine their natural frequency, damping ratio, and mode shapes under vibration. The hybrid composite with 30% banana fiber and 10% sisal fiber content exhibited the highest damping ratio of 3.681, indicating better vibration absorption. The composite with 20% of each fiber showed the lowest natural frequency of 34.312 Hz, demonstrating better mechanical stiffness at reduced mass. The study aims to optimize fiber content for improved dynamic properties in natural fiber reinforced composites.
