INVESTIGATION OF PHYSICAL AND MORPHOLOGICAL PROPERTIES OF COMPOSITE MADE OF CHEMICAL FOAMING AGENT OF NATURAL FIBER REINFORCED POLYPROPYLENE MATERIALS
 
Natural and wood fibre reinforced polymer materials are growing rapidly within the automotive industry because of their advantages such as their reducing the density of automotive components through microcellular structure, process, and product. Natural fibre reinforced foamed polymer materials are of high significance because of their ability to reduced weight and improved strength. This research investigates chemical foaming agents content on cell morphology, density, and physical properties of composites. In this study, chemical foaming agents were being reinforced at the rate of 1-2-3%wt. in natural fiber-reinforced recycled composite polypropylene raw material. Microcellular hempfibre reinforced PP composites are obtained in the injection machine were molded in sizes and shapes in accordance with the standards. Water absorption test, melt flow index test (MFI), determine density, Vicat softening temperature, heat deflection temperature (HDT), humidity test for moisture behavior, and the wear test would be done. The structures of the foamed composites were examined using scanning electron microscopy (SEM) to observed cell morphology cell size, shape, and distribution of cells account for this behavior. By examining the test results, the physical, and morphological properties of natural fiber reinforced polypropylene materials at different chemical agent percentages were examined. Optimum yield can be obtained from the results by investigating property changes.
