Natural fibers are getting attention from researchers and academicians to utilize in polymer composites due to their ecofriendly nature and sustainability. The major problem associated with these natural composites is the rapid response to moisture and the chemical attack. In this study, the effect of gel coat on jute fiber reinforced laminated polymer composites has been studied. The experiments were carried out to study the moisture absorption and the chemical sensitiveness. Also, the strength of these laminates has been identified by the edge notch tensile (ENT) test and bending test. The specimens have failed with delamination under bending loads, rather than bulk deformation. The edge crack failure in laminated specimens is unpredictable and specimen failure occurs catastrophically. So to predict the nature of failure in the presence of edge crack, edge notch tensile test is carried out and to analyze the delamination effects 3 point bending test was carried out. The prepared specimens were coated with a layer of gel coat material by roller method and categorized as coated/uncoated type. The coated specimens were further categorized as single layered, double layered and triple layered. The specimen preparation and the experimentations were carried out as per ASTM standards. The results have shown that the gel coating of specimens will improve chemical resistivity. Also it was observed that the effect of eccentric loading on the failure of ENT specimens was much contributed by tensile loads, rather than the back scattered bending loads. The failure under bending loads was attributed by the nature and the density of the delamination sites. [ABSTRACT FROM AUTHOR] |
