Abstract

Systems and methods for forming radius fillers for composite structures are disclosed herein. The systems include a sheet-locating structure that has a support surface and a support surface edge. The systems further include a separation device, a conveyance structure, and a layup surface. The methods include locating a sheet of composite material on a first support surface and translating the sheet of composite material such that a first portion of the sheet is supported by the first support surface and a second portion of the sheet extends past the support surface edge. The methods also include separating the second portion of the sheet from the first portion of the sheet to form a strip of composite material. The methods further include conveying the strip of composite material onto a layup surface and repeating the methods to form the radius filler from a plurality of strips of composite material.
