Biteam unveils combination architecture box-beams

Biteam, an internationally recognised 3D-weaving pioneer and specialist manufacturer of woven profiled materials, has developed an entirely new set of woven combination architecture box-beams, for constructions requiring structural members to withstand relatively high impact and torsional resistance, in response to specific performance demands of the automotive, engineering and building industries.

The novelty of these box-beams is their combined +/-?° and 0/90° fabric architectures to withstand different loads efficiently. While the two vertical walls have +/-?° fibre orientations, the top and bottom horizontal walls have 0/90° fibre orientations. Further, each of the four corner joints formed by the adjacent walls has a mutual through-thickness interconnection to resist delamination and increase reliability.

Tests have established that beams such as I and double flanged-triangle made of combination architectures have unprecedented energy absorption capacity and damage resilience. They even outperform competing composite and metal beams in some cases, according to a press release.

Combination architecture box-beams are producible in a range of dimensions. Presently they have been produced in a maximum cross-sectional dimension of 90x45 mm, with wall thickness of up to 6 millimetres to suit specific application requirements. All combination architecture beams are directly woven by the innovative add-on weaving technology invented by Dr. Nandan Khokar, co-founder and R&D manager of Biteam. The current prototype add-on weaving equipment is designed to produce these beams in a linear form with a maximum length of 2 metres. (GK)
