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.
Toho Tenax is introducing a high-tensile, highly shock-resistant prepreg that incorporates carbon fibre developed for aerospace applications and carbon nanotubes (CNTs).
NTPT is collaborating with the Ecole polytechnique fédérale de Lausanne - Swiss Centre of Technology (EPFL) and other partners to research discontinuous fibre composite tubes for high performance applications.
Hexcel is promoting its range of composite materials for skis, snowboards and other high performance winter sports equipment at ISPO Munich 2018 on 28-31 January.
