A research on the production of hybrid fiber and mineral reinforced high performance polymer composite material

Within the scope of the study, it has been tried to produce high performance polymer composite with high physical, chemical and mechanical properties, hybrid fiber and mineral reinforced. In the produced composites, orthophtalic and isophthalic unsaturated polyester resin as matrix, glass fibers and basalt fibers as reinforcing material, silica sand, quartz sand and basalt sand as mineral filler material were used. Experimental studies in the production of composite materials have been made in 3 stages. Experimental studies at the first stage were carried out on unsaturated polyester resin composite mixes prepared using initiator and accelerator at different ratios. In the second step, the properties of the composite materials were tried to be improved by mixing the filler materials having different types and different particle distributions into these resin mixtures individually and as a hybrid. In the third and final stage, in order to make the composite material have the best properties in all respects and consequently to produce an alternative composite material to the materials used in the existing market, as a result of the experimental studies made in the first and second stages, chopped fiber reinforcement materials of different types and different volume ratios were added in to the filled resin mixtures having the best physical and mechanical properties and providing optimum resin consumption and the ultimate experimental work was carried out on the formed hybrid fiber reinforced composite materials. As a result of the analyzes made, it has been determined that the optimum resin mixture for both orthophtalic and isophthalic resins, in which the curing temperature and polymerization can be controlled, is obtained at the rate of 1% initiator and 1% accelerator. It has been found that silica filled composites with F0,8 grain size distributon produced with orthophtalic resins with such mixing ratios consume less resin and have higher mechanical properties. In fibrous composites, it was determined that 10% glass fiber composites with "F 0.8" dispersed quartz filled have the best mechanical properties. However, it has been concluded that the "F 0.8" dispersed silica filled 10% glass fiber composites may be preferred due to their mechanical properties being good at reasonable rates and being the least resin consuming mixture.
