A method and device are disclosed for producing 3D fabrics including yarns/tows that remain in pre-tensioned condition. Further, the method and device produce 3D fabrics with features that increase the mechanical performance of produced materials which are highly suited for composite materials and impact injury mitigation applications. The method and device also provide a simple, quick and compact arrangement to produce economically both uniaxial and multiaxial types of 3D fabrics with specific dimensions and shapes in ‘middle-outwards’ manner to reduce production time by half by arranging the set of axial yarns in zigzag fashion between oppositely facing supports. The method and device aid automated production of 3D fabrics and their direct packaging to eliminate contamination of produced 3D fabrics. A 3D fabric produced in this way is also disclosed. The 3D fabric includes yarns/tows that remain in pre-tensioned condition.
