Abstract

Research shows that there is an increasing interest in alternative friction materials that do not harm human health and the environment, especially after the harmful effects of asbestos were revealed and its use was banned. This study evaluates the potential of apricot kernel shell, an agricultural waste, to be used as a bio-material in brake pad compositions. Composites containing different granule sizes and amounts of apricot kernel shell were experimentally tested for friction performance using a dynamometer. The addition of apricot kernel shell to the brake pad compositions slightly increased the noise level but improved the coefficient of friction. These findings reveal the potential of using apricot kernel shells as an economical and environmentally friendly material in brake pad compositions.
