Abstract
Technical Field: A reinforced fiber sheet used as a reinforcing material of the fiber that reinforces a composite material that is manufactured following the carding of bundled fibers. Technical Problem: Provide a carding machine that smoothly produces a carded sheet from the bundled fibers of reinforced filaments. Solution Method: One or more supportive part (254) is placed in a plane or a crescent form at certain intervals along the moving direction of the bundled fibers in a carding unit (25) to card them with a fluid before and after the supportive parts, improving the carding efficiency. Major Application: Aerospace, land transportation, shipping, building, construction, industrial parts, and sporting goods.
Claims33
A carding machine for the bundled fibers is comprised of a machine that is equipped with a feed roll wound with the bundled fibers;
- a carding unit to card the carding fibers drawn out from this feed roll with a fluid that flows in the direction orthogonal to the moving direction of the bundled fibers;
- and a rewind roll that rewinds the carded sheet that is carded in the carding unit and is characterized by the said carding unit possessing one or more supporting parts placed at certain intervals along the moving direction of the bundled fibers.
