Fiber Orientation Effect on Mechanical Properties of Coconut Leaf Midrib Reinforced Polymer Composite

ABSTRACT

This paper depicts the effect of fiber orientation on coconut midrib fiber reinforced composite material. For the experiment the collected midrib was used as reinforcing particle whereas mixture of epoxy resins and hardener performed the role of matrix. After fabrication two types of samples were prepared-0◦ specimen whose fibers were placed horizontally and 90◦ specimen whose fibers were placed vertically with ground. Flexural test, Impact Test and Rockwell hardness test were conducted on both types of specimen. Hardness showed no variation. But 0◦ specimen revealed almost 82% greater flexural strength and 59.67% higher impact strength than those of 90◦ specimen.
