The Study on Static and Dynamic Properties on Hemp Natural Fiber Reinforce Polyester Composite Material

Abstract

Mechanical properties of hemp fibers and strong laminates were determine to assess the prospect of using it as new material in engineering applications. Samples were fabricated by the hand lay-up technique (20:80 fiber and matrix magnitude relation by weight) and the properties were evaluated using the UTM material testing system. The mechanical properties were tested and howed that hemp laminate has the tensile strength of 5.5 KN, bending strength of 4.380KN and frequency and damping for healthy specimen. Results indicated that natural fibers square measure of interest for inexpensive engineering applications and should deal with artificial hemp fibers once a high stiffness per unit weight is fascinating. Results to boot indicated that future analysis towards important enhancements in compressive and impact strength of these styles of composites.Have to be required to specialize in the optimization of fiber strength rather than surface bond strength.
