Title:
A device and a method for manufacturing a solid preform for structural parts from a laying head and a charge of fibrous composite
Document Type and Number:
Japanese Patent JP6117337
Kind Code:
B2
Abstract:
A laying head for manufacturing a three-dimensional preform includes an inlet configured to feed in a plurality of dry rovings. A fiber conveying device simultaneously and mutually-independently conveys, in a fiber supplying direction, the rovings fed-in via the inlet. An outlet is arranged downstream of the fiber conveying device in the fiber supplying direction and simultaneously lays the plurality of rovings on a workpiece carrier to manufacture the three-dimensional preform. A fiber-cutting device is disposed downstream of the fiber conveying device and upstream of the outlet in the fiber supplying direction and cuts the rovings. A nozzle applies a medium onto the rovings. A slit-shaped through gap of the nozzle has a height is equal to the height of the dry rovings in the thickness direction plus a margin that is sufficiently small so as to cause the medium to be forcibly embedded into the dry rovings.
