Generic Production Process for 3D Woven Nodal Elementary and Derivative Structures.

Current state of the art within textile truss structures requires a variety of production, assembly and joining processes to conclude in a fully integrated truss configuration. This approach sees the joining and bonding of separate struts to node parts. The node is the connecting area which accommodates the strut-to-strut intersections. A production process of separate truss components (struts and nodes) inherently has constraints, such as: increased labour; bonding issues; longevity of product. In the development of a fully integrated textile truss the utilisation of conventional weaving technology and production principles allowed the development of the three-dimensional (3D) woven nodal truss structure (3DWNS). The 3DWNS’s node and nodal segmentation, defined by boundary lines provided defined areas within the weaving width, length and depth for the assignment of weave architectures. The commonalities within the production of varying strut-to-strut intersections and strut-to-strut variable dimensions within a T-shaped and K-shaped nodal configuration provide the foundations for the development of elementary nodes for other 3DWNS’s. The development of the generic procedure and application of to the 3D-to-2D-to-3D nodal structure production process and elementary nodes will be presented within this paper.
