By special manufacturing methods developed by the textile industry, it is possible to obtain a new category of 3D textile architecture called 3D textiles. These are infiltrated with a resin to obtain composite materials with reinforcing fibers in all three directions. The resulting composite material can be processed as a solid 3D bulk material that is then machined to shape or processed directly into the final shape of the desired product. 3D textiles can be made as 3D weaves or 3D braids.

To overcome these drawbacks, there is always a need for designing structurally integrated textile preforms and a promising technique to engineer and deliver the same. Today, the inspiration for presenting 3D-textiles in composites is not just to expand the out-of-plane properties, but additionally, to decrease the assembling work expense and to integrate more functionality into the component (Behera & Dash, 2014; Chen, Taylor, & Tsai, 2011). The weaving processes makes it possible for the usage of different types of yarns and weave patterns in various parts of the preform, rendering the design space enormous and more versatile for structural applications. M. Fazeli et al. (2016) developed a flexible weaving process considering the weft sequences and systematic weave pattern for manufacturing complex 3D woven structures on a shuttle loom. Various 3D woven profile fabrics in the shape of ‘H,’ ‘Y,’ ‘Π,’ ‘T,’ ‘ + ,’ etc., and their production technique have been patented based on the concept of single and multi-layer weaving (Abildskov, 1988; Ono, 1987; Palmer & Micheaux, 1983). These structures are developed with two or more sections of fabrics interwoven with the base fabric and the line of intersection runs along the longitudinal direction of the fabric. These techniques are suitable for producing individual beams and stiffener structures and most of the previous researchers have also focused on the development of such lengthwise profile structures (Dambrine, Godon, & Perroux, 2016; Godon & Dambrine, 2017; McClain & Goering, 2016). Torun, Mountasir, Hoffmann, and Cherif (2013) and Mountasir et al. (2013) focused their work on the development of the technological construction and industrial size manufacturing of woven preforms using face to face weaving technique (Terry weaving). The technique involves the development of preforms with profile sections integrated into the base sections in longitudinal and transverse directions and are suitable for designing composite panels with integrated orthogonal stiffeners (Torun, 2011). However, the work on converting them into composites and studies related to their mechanical performance and structural suitableness is yet to be reported.
