Process to reduce sticking during surface treatment of graphite articles

Abstract

Processes and systems to reduce sticking of graphite materials and particularly resin impregnated graphite materials to forming tools, such as an embossing roller, during a process of manufacturing articles from the graphite materials. In one embodiment, an aerosol spray non-stick material is intermittently sprayed upon the embossing rollers. In a second embodiment, one or more sheets of thin flexible solid non-stick material, such as polyethylene, are sandwiched between the graphite material and the embossing rollers. The system is particularly useful for manufacturing material useful in producing components of fuel cells.
