Abstract
Official abstract text for this publication.
An apparatus for forming a bend in a composite panel is provided. An angle and a radius bend are identified for a bend. A location of the bend in the composite panel is identified. A slot is cut having a curved flange in the composite panel at the identified location in a single pass through the composite panel with a tool, wherein the curved flange has a shape with a bend allowance width and a bend slot width. The bend allowance width is BA=2π*A/360, wherein BA is the bend allowance width, R is a corner radius, and A is a bend angle. The bend slot width is BS=BA−2K(R−T), wherein K is Tan(A/2) and T is a thickness of the composite panel.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite panel comprising: a first layer; a filler layer; and a second layer, the first layer, the filler layer, and the second layer forming the composite panel having a first side and a second side, wherein a slot having a curved flange is present within the first layer and the filler layer, the slot having a bend slot width, the filler layer having a first curved surface characterized by a first radius and a second curved surface characterized by a…
