Damage mechanisms of the marine composites subjected to impact loading

In this study, impact behavior, of jute ? epoxy composites with various thicknesses were investigated.Composite materials today very widely used. Among them are marine transportation, aeronautics and defense industries, land transportation, space programs, energy sector, infrastructure, building industry.Composite materials are especially favored in yacht and boat construction due to their high water resistance, relative low weight compared to metals, easier and cheaper production.The aim of this study was to problem to produce composite materials using a reinforcing element with natural fiber, and woven cloth produced from jute plant was used. Jute is a fibrous plant, has antistatic properties and is economic to produce.Jute ? epoxy composite material needed for the experiments was produced as a single plaque with six different thicknesses. The produced layer was cut in 100x100 mm. Initially 10J impact energy was applied to each sample and it was increased 10J for each experiment until piercing damage occurred in the sample. Each experiment was discussed with resulting graphics and photographs and then results of all the experiments were discussed comparatively.It was seen that as the sample thickness increased, so did the energy needed for sample to sustain damage the graphic of samples thickness depending on piercing threshold energy was drawn. The resulting curve was linear and it makes it possible to reach various results.Keywords: marine, natural, composite, impact
