FLEXURAL BEHAVIORS OF SANDWICH COMPOSITES PRODUCED USING RECYCLED AND NATURAL MATERIAL

Recently, for making the low-cost engineering materials the use of natural fibers as reinforcement in polymers composites has brought forth a lot of interest. The use of natural products instead of synthetic materials reduces the amount of carbon released into the atmosphere. Nevertheless, reuse of used materials by recycled is important both for the environment and for economic reasons. In this study, flexural behaviors of sandwich composites manufactured by using natural and recycled material were investigated. In this context, 9 different core materials, which were made by using 3 different granules size (1 mm, 2 mm and 4 mm) and 3 different core thickness (4 mm, 8 mm and 12 mm), were manufactured from waste vehicle tires. After, sandwich composites were produced by combining the core materials with natural jute fabric reinforced laminated composites. In order to test the usability of the produced sandwich composite materials as building material, the flexural behaviors of the sandwich composite were investigated under three-point bending load. Test results show that flexural behavior of the material varies according to the granular size and thickness of the core material
