DEVELOPING A TECHNOLOGY FOR OBTAINING ASBESTOS-FREE BRAKE PADS WITH REQUIRED FUNCTIONAL PROPERTIES

Abstract

In the work, as a result of theoretical and experimental research, the principles of creating asbestos-free composite brake materials with required functional properties are developed using fibers and powders obtained from RA mining and metallurgical production waste under the conditions of high-temperature short-term-repetitive regime. The structural transformations of the surface layers under high temperature contact conditions, and modeling of the structuring mechanism are performed.

For the first time, a program for automatic calculation of specific heat capacity coefficients of composite contact materials with functional properties, depending on the volume content of the components, is developed for the first time, with accessibility in the Windows software environment, displaying the import and export fields of the program in the winforms method. The thermophysical and endogenous properties of fayalite (Fe₂SiO₄) contained in the slags of Alaverdi copper smelting production and its use as a regulator of functional properties in brake contact compounds are revealed. A new multi-component brake, Bastenit-10 polymer-based asbestos-free brake heat-resistant composite contact material using fayalite (RA Invention Patent N 752Y, 2022) and its production technology are developed.
