Abstract
A joining structure adapted to join adjacent tube structures together while providing high strength with low weight. The joining structure may be of composite materials, and may include warp tows in the longitudinal direction of the tubes and have weft tows cross-woven into a fabric, which may be a carbon fiber. The joining structure may be Y-shaped and adapted to join three composite sheets together. The weft tows may also be wound around a central cluster of tows, or tows, which may provide extra strength. The tubes may be pressurized in use, such as in an aircraft fuselage.
