Pneumatic induction fiber spreader with lateral venturi restrictors |
摘要 |
A machine for producing a graphite fiber tape suitable for use in the production of metal matrix composites by physical vapor deposition. The machine consists of adjacent air-tight enclosures. Two venturi pipes are located within the enclosures and aligned with a gap between them. A vacuum pump draws air out of one of the air-tight enclosures. Graphite fibers are drawn through the venturi pipes and laterally spread from a tow bundle via the Venturi effect to form a thin tape.
