JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Biteam has developed a new 3D woven T-Bar profile which comprises a fully integrated single-piece T beam with a solid square / rectangle bar at the tip of the T profile’s web. The T-Bar has been developed for enabling a jointing system that functions as stiffener and supporter.
Biteam, pioneer of 3D-weaving technology, has developed a new 3D 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. The T-Bar has been developed for enabling a jointing system that functions as stiffener and supporter for producing large structures, just as found in woodwork.
As illustrated, the T-Bar is designed to fit with a cross-member having a matching cutout so that the two lock mechanically. Through such a jointing, composite material floors, covers, gates/doors, planar and curved walls/bodies etc. could be constructed for building/construction, aeronautical/aerospace and engineering applications. The T-Bar thus uniquely enables different constructions.
The cross-members can be chosen to be either slats or profiled beams such as T, I, U etc. according to specific application needs. Such cross-members, having cutouts matching with the cross-sectional shape and dimensions of the T-Bar, when slid over the T-Bar beam, create the jointed structure. By arranging a number of T-Bars parallel to each other and sliding cross-members over them, as shown in inset, a grid-like jointed structure is produced which can be either bonded or fastened.
Suitable panels/sheets can be fixed at either one or both sides of the jointed structure to manufacture the required products. T-Bar beams and cross-members are producible in different dimensions according to application needs. The expected advantages of the new T-Bar jointing system are:
- One-piece construction - no ‘noodles/fillers’, plying and stitching required.
- Flat sides of the T-Bar provide large bonding/fastening surfaces.
- Improved structural rigidity and reliability.
- Flexibility in construction.
- Customized performance.
- Reduced constructional labour, time and cost.
Biteam is a Swedish company specializing in designing, developing and producing fully integrated singlepiece high-performance 3D woven profiles for load-bearing structural applications.
The novel 3D woven T-Bar will be displayed at JEC Show 2011, Stand C37.
Here are few examples and update of these two techniques which can be seen in many application sectors now.
