The study investigates the thermo‐mechanical properties of isotactic polypropylene (iPP) hybrid composites in reference to various amounts of particle‐ and fiber‐shaped inorganic fillers. Three grades of hybrid composites were prepared as a function of filler amount: 5, 10, and 20 wt% and different ratios of glass fiber (GF) and calcium carbonate (CaCO 3 ). The main objective is to describe the relationship between the hybridization efficiency and mechanical performance of polypropylene‐based composites. The analysis of the thermo‐mechanical properties of the composites shows that both the total amount of the filler and the ratio of GF and CaCO 3 clearly influence the properties of the composites. Hybrid composites with the highest amount of the GF display improved thermo‐mechanical stability. The presence of well‐dispersed CaCO 3 in the composites was found to improve elongation at break and Vicat softening temperature values. Even though it is glass fiber, which shows higher filler effectiveness and visibly reinforces the composite samples, causing an increase in tensile strength or reinforcing efficiency, replacing up to 50% of this filler with calcium carbonate does not result in a considerable deterioration of the properties of the material.
