ABSTRACT:
An apparatus for making composite sheets that are homogeneous, dense, and have an even surface. The apparatus comprises an oscillating plate unit that vibrates in a direction transverse to a belt means. Composite pre-mix is deposited on the conveyor belt which draws it under the oscillating plate. The oscillating plate has three sections: a curved plate section; an inclined plate section and a flat plate section. The composite pre-mix is metered by the curved plate section, compacted by the inclined plate section and maintained compacted by the flat plate section. These thus formed composite sheets may be cured and are particularly adapted for use in fuel cell structures such as electrode substrates.
