Investigation of mechanical and tribological properties of boric acid reinforced composite plates

In this study, the mechanical and tribological properties of unidirectional glass fiber/polyester resin and unidirectional carbon fiber / polyester resin composite materials reinforced with boron particles have been investigated by experimental methods. Composite plates were produced by hand lay-up method using polyester resin mixed with boric acid particles (H3BO3) with a specific gravity of 1.51 g/cm3 and a molecular weight of 61.83 g/mol, which were utilized as boron particles. As particle reinforcement, 1%, 5% and 10% boron oxide polyester resin mixture was obtained. The effects of particle reinforcement on mechanical and tribological properties were investigated. As a result of the experimental studies, it was determined that, due to the increase in the particle ratio, the wear resistance increased by between the ratios 5% and 50% in some samples compared to the samples not reinforced with boric acid particles and the tensile strength improved up to 32% in some samples.
