Abstract :In this study, the quality performance, compressive strength, surface hardness, electrical conductivity, and life cycle assessment insert ignore into journalissuearticles values(LCA); of the composites produced by reinforcing tincal insert ignore into journalissuearticles values(Na2B4O7.10H2O); into polyester and vinylester resins at different rates have been determined. Tincal ore, which is ground with a particle size of 74-149 microns, is dried in an oven at 105 °C for 2 hours and then added to the resins at the ratios of 0 wt.%, 1 wt.%, 2 wt.%, and 3 wt.%. According to the results obtained, it has been determined that the compressive strength and Shore D hardness of the composite raises as the tincal mass ratio increases up to certain amounts. According to the mechanical test results, it is found that 3 wt.% tincal reinforcement maximized the compressive strength of the polyester composite, and 2 wt.% tincal reinforcement maximized the compressive strength of the vinylester composite. In the electrical conductivity test results, it is seen that the first relaxation time of the polyester composite is 2.14·10-4 s and the relaxation times of vinylester composite vary between 10-4 and 10-6 seconds. LCA results showed that vinylester composite had more environmental effects than polyester composite except for ozone layer depletion insert ignore into journalissuearticles values(ODP); effect. Although there is a partial increase insert ignore into journalissuearticles values(<0.5%); in the environmental impact of composites with tincal reinforcement, it is thought that the increase in the technical performance of the composites will tolerate this partial increase.
