3D composites have potential applications in aerospace, space and defence sectors. Skin- stiffener elements in wings, aircraft and spacecraft root fittings, armors, helmets & bullet proof vests, engine components such as nozzles, exhaust cones, convergent-divergent flaps, etc.. are the potential areas of interest for 3D composites. These composites have the ability to improve the out-of-plane properties which has been one of the challenges currently faced by composite designers. The interweaves of the 3D reinforcements in the composite will hold the structure together when subjected to thermal shocks and exposure to high temperatures. Also, it has been shown that the stress analysis conducted on a 3D composite has isotropic thermo-mechanical loading regime. This paper details about the development of 3D weaving technologies for use in composites keeping the above applications in hindsight. The focus of the work is on single layer profile weaving for inserts, angle interlock and noobing technologies for integrated thick structures and 3D weaving technology based on dual-direction shedding principle for integrated thick profiles used in fittings.
