In modern automotive clutch systems, various friction materials are used, which are playing a crucial role in transfer of power in different types of engines and machines. In this study, a G95 woven frictional material was subjected to different working conditions over a time sequence in order to evaluate the generated frictional force and the coefficient of friction. It was fabricated frictional disc samples with inner and outer diameters of 30 mm and 38mm with 3.5 mm thickness of G95 friction material to perform the frictional tests using XTM 500 test rig at different surrounding temperatures (300 K° and 380 K°). The range of applied normal load was between (100-300 N) and the rotational speed was 300 rpm. The achieved results showed that both friction force and coefficient of friction are highly affected by the applied load and the surrounding temperature of the frictional system especially at the high level.
