Biteam AB (Bromma, Sweden), a developer of 3-D weaving technology, has introduced a new 3-D woven T-Bar profile. This preform comprises a fully integrated single-piece T-beam with a solid square/rectangle bar at the tip of the T-profile’s web. Developed to enable a jointing system that functions as stiffener and supporter in large structures, similar to that found in woodwork, the T-Bar is designed to fit with a crossmember that has a matching cutout, enabling a mechanical lock between the two segments. According to the company, this joint type enables construction of composite floors, covers, gates/doors, planar and curved walls/bodies in building/construction, aeronautical/aerospace and other engineering applications. The crossmembers can be either slats or profiled beams (T, I or U shapes), per application needs. The jointing system reportedly improves structural rigidity, increases design flexibility, reduces labor and makes it possible to customize structural performance. Further, the T-Bar’s flat sides provide large bonding/fastening surfaces.
