Biteam AB (Bromma, Sweden), a developer of 3D-weaving technologies, will feature the first ever weaving technology that is capable of directly manufacturing beam-like 3-D profiled materials wherein the orientation of fibres constituting the web and flange are +Ɵ°/-Ɵ° and 0°/90°. Such beams have their webs/flanges fully intersecting in mutually through-thickness directions to render the junctions delamination-resistant. Further, the fibers constituting the web and flange are integrated to impart structural stability for enabling handling and impregnating. Bitem says these features jointly render the novel woven profiled products uniquely capable of bearing shear and tensile loads. Dr. Nandan Khokar, inventor of the weaving technology, says, “This development has been particularly directed at weaving fully integrated objects, for example the wing of an aircraft, complete with skin and stiffeners/ribs, in one step to quicken manufacture of reliable and consistent composite materials.”
