ABSTRACT:
The present invention is embodied in an tool and method for structurally applying fiber stiffeners to a material. The tool inserts a plurality of fibers embedded in a transfer material through a hat stiffener and into a substrate and includes a first head, a second head, and a handle. The first head is defined by a roller having first edges and a center cutout. The cutout corresponds to the thickness of the transfer material. The second head is located at a distal end from the first head and is defined by a roller having second edges and a center groove. The groove corresponds to a thickness associated with guiding the tool along the corner of the hat stiffener. The first and second edges conform to the surface of the substrate. The center handle is coupled between the first head and second head for gripping. The first head is adapted to initially drive the fibers embedded in the transfer material through the hat stiffener and into the substrate. The second head is adapted to finally secure the fibers within the hat stiffener and the substrate.
