Abstract

A method of manufacturing a cured composite structure includes inserting a plurality of radius filler segments into a radius cavity extending along a length of an uncured composite base member to form an uncured structural assembly. The plurality of radius filler segments are placed in end-to-end arrangement within the radius cavity and each having opposing segment ends and being formed of a thermoplastic material. The method additionally includes heating the structural assembly at least to a base member cure temperature that causes the segment ends of end-to-end pairs of the plurality of radius filler segments to fuse together and form a continuous radius filler element that extends along the length of the composite base member. The method also includes allowing the structural assembly to cure to form a cured composite structure.
