Hybridization is a combination of two or more types of fibers in one matrix and it is becoming more and more common. Hybridization overcomes the limitations of one type of reinforcement by combining with another type with a better performance. This allows for a more versatile use of composites with improved properties. Our research aimed to develop and characterize the polypropylene hybrid composites reinforced with basalt and glass fibers. The fillers were added in weight content of 10%, 15% and 20%. The composites were produced by using an injection-molding machine. To measure the mechanical properties of the hybrid composite a tensile test, three point flexural test and Charpy impact test were conducted. Furthermore, the tests were performed at various temperatures (−24 °C, 23 °C, and 80 °C). To evaluate the state of dispersion and adhesion between the fibers and the matrix, the fractured sur-faces of the various samples after tensile test were observed using a scanning electron microscope. The results show that the production of composite with both basalt and glass fibers in polypropylene matrix with maleic anhydride-grafted polypropylene can be successfully achieved. The addition of two types of the fibers increased the tensile strength by 306% and tensile modulus by 333% for a composition with 20% by weight fibers
