Abstract
The paper presents the results of experimental research conducted in the laboratory with the aim of obtaining new composite materials used for automotive brake pads. The friction material consists of seven components; five of them were kept in a constant proportion (60%wt), and two (40%wt) were varied in fraction volume, namely phenolic resin and hemp fiber. For each recipe, the effect of phenolic resin on density, porosity, hardness, thermal stability, and friction-wear characteristics was analyzed. The study indicates that finding the optimal balance between phenolic resin and hemp fiber constitutes an efficient approach in improving friction performance. Additionally, the study demonstrates the viability of organic composite materials in braking applications, as they are capable of meeting the performance levels established by traditional materials.
