FIELD: machine building. ^ SUBSTANCE: invention relates to friction products, particularly, to blocks and linings of the vehicle disk and drum brakes. The proposed friction product includes a polymer composite friction element with ferromagnetic particles from magnetically soft material. Additionally, it comprises the particles of magnetically hard material with the ratio of magnetically soft-to-magnetically hard particles making from 1:1 to 1.5:1, respectively. As a result, friction properties are improved due to accelerated stabilisation of friction characteristics during initial operation in, primarily, out-of-town conditions. This has been achieved because of constant heating of proposed product during reversal magnetisation under temperatures that cause no fast destruction of friction composite polymer matrix. ^ EFFECT: improved friction properties. |
