3-D weaving pioneer Biteam (Bromma, Sweden) displayed the first produced sample, an I-beam demonstrator, made using a new weaving technology capable of directly manufacturing beam-like 3-D profiles in which fiber orientations in the web and flange are, respectively, +θ°/-θ° and 0°/90°. Developed for the aerospace, aeronautical, motor sports, automobile, engineering and building/construction markets, the beam’s web and flange fibers intersect in the z-direction (through the thickness), making the preform delamination-resistant and, thus, more capable of bearing shear and tensile loads as well as imparting structural stability during premold handling and impregnation steps. The technology’s inventor, Dr. Nandan Khokar contended, “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.”
Editor PickStrata, Reliance form partnership to advance aerospace composites
The partnership will look at opportunities in the production of carbon fiber aerostructures, prepegs as well as 3D printing of aerospace components and airframe panels.
