Mechanical Properties and absorption behavior of CSP Filled Roselle Fiber Reinforced Hybrid Composites

This article depicts the mechanical properties and hydrophilic behavior of a new class of multi-phase composites consisting of vinyl ester resin reinforced with roselle fiber and filled with coconut shell particulates (csp). fiber reinforced vinyl ester composites was prepared by incorporating coconut shell at four different filler contents viz. 0%,5%,10%,and 15%. the mechanical properties of these composites are evaluated. the results show that the tensile and impact strength of the composite increase with increase in coconut shell content,the flexural strength of the composite is a maximum of at 5% of the csp filler content. the water absorption goes on increasing with increase of time duration and csp filler content. the maximum of water absorption is obtained from the composite prepared with 15% csp filler. the hardness and density of the composites are also greatly influenced by the content of these fillers.
