An innovative prototype composition of a composite friction material was developed. The actual values of selected parameters were determined, as described in a previous paper. It was decided to verify whether the proposed material differs from conventional materials in terms of temperature characteristics, and if so, to what extent. For this purpose, numerical studies were performed using the problem of initially boundary thermal conductivity. The braking system of a popular passenger car was used as the object of the research. A mathematical model of the studied phenomenon was developed, which was implemented in a virtual environment. The results showed that changing the reinforcement method to a more ecological one than the conventional one does not cause significant changes in the temperature profiles obtained for the adopted braking scenario.
