Investigation of the mechanical and physical properties of glass powder and talk filled polypropylene composites

Today, the role of composite materials in the field of plastic material production is quite large. Composite materials are formed by improving the properties of the polymer by adding one or more filling materials to the polymer material used as the main matrix. In this study, the change in the mechanical and physical properties of the polymer by adding different fillers to the polypropylene material was examined. Nano micron sized talc and glass powder were used as fillers. 6 different types of composites formed with fillers were mixed in different proportions in the extruder. Only 3% talc was added as the first mixture to the original raw material PP product. Then, 5%, 10%, 15%, 20% glass powder was added by keeping 3% talc amount constant. The prepared mixtures were produced as samples for various tests by injection molding method. Tensile, impact and bending tests were performed on the produced composite samples, and their properties were examined using DSC, FTIR and TGA devices and the changes in their values were observed. As a result of the tests applied to the samples produced by the injection molding method, it was observed that glass powder and talc fillers produced different results on the physical and mechanical properties of the polypropylene material. In the tensile test results, it was observed that the elastic modulus value in the sample to which 5% glass powder was added reached the saturation point and reached the level of 712.82 MPa. It was determined that the elastic modulus value decreased after this value. In TGA/DTG analyses, it was observed that the decomposition onset temperature increased with the addition of talc. Fluctuations in temperature values were observed with the addition of glass powder.
