Threedimensionally woven textiles are not only beautiful, they also have thepotential to change the way aircraft and other complex structures are built. Differentauthors define 3D fabrics in different ways. Greenwood 3D fabrics are thosefabrics which have substantial measurement in three dimensions as compared tothe conventional fabrics, which will have measurement in two dimensions only. Accordingto Khokar 3D fabric is defined as a single-fabric system the constituent yarnsof which are supposedly disposed in a three mutually perpendicular plane relationship;this definition doesn't consider multilayer and some other type of fabrics tobe of 3D type. Hearle gives definition of 3D fabrics as 3D fabrics are thickplanar sheets or shaped solid forms with multiple layers of yarns, hollow structuresand thin 3D shells.
