The aim of these experiments is to determine the best way to obtain high mechanical properties for phenol resin and glass fibers based composites. Various ways of fabricating the material were studied, as well as its best composition. The conditions of drying, molding processes were optimized. From the most conventional method, using ethanol as a solvent to newer ones, including continuous ways of processing and the use of water instead of ethanol, a lot of possibilities exist to produce such a material. This paper explains the advantages and drawbacks of a whole range of manufacturing processes.

Two-layered clutch plates manufactured by a new process using BMC show a significant deflection. Two methods solving such deflection were alternatively developed in this study. Changing the composition of the clutch plate appeared to be useless while after-curing on deflected clutch plates was effective. Thermal cycles or high pressure for after-cure did not reduce the deflection. However, applying after-cure with a sloped mold reduce the deflection without increasing the disk density.
