Natural and organic-based composite materials are widely used in many industrial applications due to
their low cost, easy recyclability, economic feasibility, and ready availability. In this study, a polymerbased
composite friction material consisting of Hemp-Colemanite composition (HCFCo) has been
developed for the automotive sector to exhibit lower cost, environmentally friendly characteristics,
and suitable friction-wear behaviors. For this purpose, three different ratios (%4,%8and %12) of
HCFCo composites were produced using a coating technique called impregnation process with a
specially designed device. During the production stage, homogeneity of the composites was ensured,
and then the final shape was given by the hot pressing method. Local based natural materilas
frequently used for as anon-asbestos friction materails. For this reason, hemp and colomanited based
composites were tested. Properties such as hardness, density, water and oil absorption, friction
coefficient, and specific wear of HCFCo samples were examined. In addition, the microstructures of
HCFCo composites were investigated to determine the bonding form between hemp fiber and
colemanite. The results obtained revealed that the friction coefficient values decreased with an increase
in temperature, while no significant change was observed in hardness and density values. Throughout
the entire testing process, the friction coefficients varied between 0.14 and 0.29 on average. It was
concluded that the developed fiber-reinforced composite can be reliably used in industrial
applications and can contribute significantly to innovations in the literature.
