Investigations of mechanical properties of natural fiber reinforced composite materials

The purpose of this study; examine mechanical properties of defined mixed composite metarials (with epoxy matrix) supported by wool, linen and cotton fabrics. For this purpose, using jute, linen and cotton fabrics with nine storey, different ratio and sorting, produced four kind of composite plate. Also produced three composite material which are different coefficients with only using glass fiber. For this composite plates production have used infusion supporting vacuum. These composite plates have been tested for pulling and impact tests to determine mechanical properties with prepared samples. Result of pulling tests created graphics -belonging to samples- These are; power-stretching and stresstransfiguration graphics Consequently; using nine storey different natural fabrics and glass fiber, these plates are less stronger than 2,3 and 4 storey produced only using glass fiber plates. This situation shows us natural fabrics, glass fiber blocking glue epoxy resin. Other result, increasing energy level for impact test. Compared absorbed energy, nine storey different natural fabrics and glass fiber plates have much absorbed energy than 2,3 and 4 storey produced using only glass fiber plates.
