The physicomechanical and technological properties of polypropylene-based composites filled with basalt fibers (BF) and glass microspheres (GM) are studied. It is shown that the introduction of short BFs and glass microspheres into PPs while ensuring good “fiber-matrix” adhesion by adding maleic anhydride-grafted polypropylene (MAPP) leads to a significant increase in the elastic modulus and tensile yield strength. The impact strength of composites improves with increasing fiber content in the presence of GM. The melt index and thermomechanical stability of the developed composites increase.
