Abstract

There is provided in an embodiment a composite radius filler for a composite structure. The composite radius filler has two or more radius laminates. Each radius laminate has a laminate of stacked composite plies formed in a desired radius with a desired radial orientation of the stacked composite plies substantially matching a radial orientation of adjacent stacked composite plies of a composite structure surrounding the two or more radius laminates. Each radius laminate is preferably trimmed to have at least one side align adjacent to the others to form a composite radius filler having a shape substantially corresponding to a radius filler region of the composite structure.
