Shaping a radius filler against a mandrel

Abstract:

A radius filler material positioned at an intersection of a mandrel and a placement surface is heated to form a heated radius filler material. Mechanical pressure is applied to the heated radius filler material to shape the heated radius filler material to a shaped radius filler having a desired shape against a radius of the mandrel. A composite ply is applied over the mandrel and the shaped radius filler.
