Biteam has applied its 3D-weaving technologies to demonstrate the direct production a 3D woven truss structure.
The 3D-weaving process’ high flexibility allows engineering trusses directly in both horizontal and vertical directions of a profiled cross-section. Trusses are created using required number and size of vertical and horizontal wefts that interlace with warps. Such a 3D woven construction produced using carbon fibres is aimed to lend bending stiffness in two mutually-perpendicular directions.
Profiled 3D woven beams having cross-sectional shapes such as H, I, T and square, together with trusses in horizontal and vertical directions, hold the potential to further lower the weight of composite materials in load-bearing applications. The 3D-weaving process allows controlled placement of required number of yarns and in desired truss angle to meet different application needs.
