Effect of coconut shell particles, coir fiber and husk powder on static & dynamic characteristic of polymer composites

Abstract

Polymer composites based on agriculture waste or wood industry waste are becoming popular due to better utilization of natural wastes and availability of low cost material for structural and dynamic applications. Availability of coconut shell, coir fiber and husk powder have attracted the development and characterization of coconut reinforced wood plastic composites. Coconut shell particles have capability of introducing the behaviour of particulate composites and coir fibers have the capability of long fibers. But chopping of coir fiber into small sizes and crushing coconut shell into various sizes of particles is the source of managing the structural and dynamic properties. Husk powders consist of very fine and light particles. So, reinforcing husk powder into polymer matrix would enhance the properties of polymer. Various samples consisting of these coconut fruit waste were fabricated for structural and dynamic characterization. Effects of these elements were evaluated. Non-contact type vibration measuring system-Laser Doppler Vibrometer was used for better accuracy in results in dynamic characteristic
