Composite stringer and methods for forming a composite stringer

Abstract:

A composite stringer assembly includes a composite stringer and a radius filler. The composite stringer includes a skin flange, a web, a corner portion extending from the skin flange to the web, an inner surface, and an outer surface. At the corner portion, the outer surface is defined by a first radius of curvature, which is substantially constant between the skin flange and the web. The support structure includes at least one of a skin of a vehicle or a base charge. The radius filler includes a first surface coupled to the inner surface at the corner portion, a second surface configured to couple to the support structure, and a third surface extending between the first surface and the second surface. The first surface of the radius filler is defined by a second radius of curvature, which is substantially constant between the second surface and the third surface.
