Analysis of Mechanical Properties of Coir/Portland Pozzolana Reinforced Polymer Matrix Composites

The current analysis deals with the fabrication of the composite sheets with the epoxy reinforced with natural fiber, Coir and the Portland pozzolana. In today’s time composite material plays a very important role in engineering application. we can replace the wood with the composite, even the composite is a recyclable. Fields like the aerospace and automobiles sectors always need the lighter weight material with good strength. Many of the parts are complex which can be made by the forming process. A matrix is prepared by using epoxy resin and when it comes to the reinforcement material it could be the natural or artificial fibers. In this we have used the coir (coconut husk) and Portland pozzolana particles. To make the composite traditional hand lay-up process method was used. After that mechanical performance was analyzed by testing the flexural strength and impact strength of samples. Polymer matrix composite is light weight with the good strength and have various mechanical abilities. It is found that coir/epoxy composite sample plates have the higher flexural strength and impact strength, and Portland pozzolana have the highest flexural modulus which proved that abovesaid composites are great alternatives to wood and plastics and over other metals.
