Polypropylene (PP) polymer, which is one of the indispensable materials of our daily life and stands out with its lightness, low cost and chemical resistance properties in the industry, was used. In industrial applications where the properties of polymers without additives are not sufficient, composite materials are produced by adding some additives to the polymer. In this experimental study, the mechanical properties of composites produced by adding boric acid (BA) to PP polymer at 5 wt.% (PP/5BA), 10 wt.% (PP/10BA) and 15 wt.% (PP/15BA) ratios were investigated. the effect of both BA filler and optimum BA filler ratio on mechanical properties were investigated. In the production of PP/BA composites, granules were first produced in an industrial twin screw extruder. Then, PP/BA composite tensile and impact test specimens were moulded on a conventional injection moulding machine. As a result, it was observed that the tensile modulus, tensile and yield strength of the composite materials decreased with increasing boric acid filler content in PP polymer. Depending on the boric acid filler content, the tensile strength decreased by an average of 18.3% and the breaking strength decreased by 14.8%. The lowest tensile modulus was obtained with a value of 2713 MPa at 10wt.% boric acid filler addition. The impact strength increased slightly at 5 wt.% boric acid filler addition and decreased at 10wt.% and 15wt.% boric acid filler addition.
