Abstract

Radius fillers for composite structures, composite structures that include the radius fillers, and systems and methods of forming the radius fillers. The systems and methods may be configured to create a pre-form that may be utilized to form a radius filler and/or create a radius filler from the pre-form. Creating the pre-form may include extending a plurality of lengths of composite tape from a composite tape source and receiving the plurality of lengths of composite tape in a pre-form forming structure, converging and/or otherwise combining the plurality of lengths of composite tape within the pre-form forming structure to produce the pre-form, and/or withdrawing the pre-form from the pre-form forming structure. Creating the radius filler from the pre-form may include receiving the pre-form in a radius filler forming structure and producing the radius filler from the radius filler forming structure.
