The fibers from the natural sources (plant, animal) provide better advantages such as less cost, high specific properties, non-toxicity, strength, and minimum waste disposal problems over synthetic reinforcement materials. The aim of this work is to fabricate coir fiber-based hybrid polymer matrix composites and to study the vibration behaviors. A hybrid polymer matrix is prepared by blending natural resin (cashew nut shell liquid) with isophthalic polyester resin. The coir fiber is treated with NaOH, KMnO4 and KOH alkali solutions to improve its adhesiveness and strength before its reinforcement with matrix. The concentration of NaOH, KMnO4 and KOH in the alkali solution and duration of treatment of the fiber in the alkali solution have been varied and its effect on the vibration behaviors is studied. Using the ANOVA technique, the influence of different parameters on the Vibration test is investigated, and a regression equation will be obtained indicating the influence of parameters.
