The evolution of BFCs from asbestos-based materials to safer alternatives is studied, and an analysis is performed to develop alternative material combinations. The critical roles of key components — fi bers, binders, friction modifi ers and fi llers — in creating durable brake friction composites for brake systems is emphasized. A composite material based on basalt fi ber with calcium carbonate fi ller is compared to a composite material based on aramid fi ber with barium sulfate fi ller through pin-on-disc tribological testing. Based on the test results, it is determined that the alternative composite materials show promise for application in brake systems. This work also provides a foundation for further development of eco-friendly brake friction composites by selecting optimal formulations. The present work defi nes an approach for subsequent research aimed at varying the components and their ratios in the creation of composite materials. This research will further improve the functionality of automotive brake systems. Purpose of the work: this research is focused on the development of non-asbestos brake friction composites (BFCs) with the goal of improving the safety and performance of automotive brake systems. Eco-friendly alternatives to asbestos are investigated, and the roles of fi bers, binders, friction modifi ers, and fi llers are analyzed. The objective of the research is to identify optimal formulations for creating durable, sustainable brake materials, paving the way for further implementation of innovative solutions in practice. Methods of investigation: a pin-on-disc tribological method is used to evaluate wear, friction, and durability, as well as to assess the suitability of the developed materials for use in brake systems. This research is dedicated to analyzing the infl uence of components (fi bers, binders, friction modifi ers, and fi llers) on the properties of friction composites for brake systems. Two compositions were experimentally studied: basalt fi ber with calcium carbonate and aramid fi ber with barium sulfate. Results and discussion: the results of the research demonstrate the eff ectiveness of using basalt fi ber with calcium carbonate and aramid fi ber with barium sulfate as components in friction composites for brake systems. It is shown that these materials provide high levels of wear resistance and friction performance. The potential for further optimization of compositions to improve eco-friendliness and enhance the operational properties of braking systems is emphasized. The obtained results also highlight the importance of component selection for the development of safe and sustainable brake friction composites. For citation: Kate N., Kulkarni A.P., Dama Y.B.
