Abstract

A method for fabricating a composite panel includes providing a preform including a peripheral edge portion and a central portion. The central portion has a first thickness, the peripheral edge portion has a second thickness that is greater than the first thickness, and a first step is arranged between the central portion and the peripheral edge portion. The method includes providing a tool including a binder defining a second step, an upper punch, and a lower tool; arranging the preform between the binder and the upper punch and the lower tool; shaping the preform using the tool; and injection molding the preform in the tool to create the composite panel.
