As a world leader in glass science, Owens Corning possesses a proud heritage of developing many influential innovations in the history of the glass fiber industry including E-glass, the Advantex brand, and an array of high-performance glasses. Owens Corning is also a world leading supplier of glass-based technical fabrics providing a full range of woven, knitted, and non-woven technologies to the global composites industry. This powerful combination of expertise in glass science and chemistry, and state-of-the-art facilities enables our team to work in partnership with our customers to develop glass-specific, tailor-made technical fabric solutions for a wide These efforts are supported by a worldwide manufacturing platform spanning more than 30 facilities and 6 research and development centers ensuring proximity of locally engineered and tailored solutions for our customers. Furnace & glass science Innovative chemistry Reinforcement solutions Global platform Redefining Multiaxial Non-Crimp Fabric (NCF) Reinforcements Multiaxial reinforcements are fabrics composed of two or more plies, or layers of unidirectional fibers, the optimal reinforcement configuration. Each individual layer can be oriented in a different axis and for this reason the fabric construction or assembly is referred to as multi-axial. Depending on the number of layers and varying orientation and axis, a unidirectional, bi-axial, tri-axial and quadri-axial architecture can be assembled into one Non-Crimp Fabric system. The various layers are held together with a stitched thermoplastic (TP) yarn - typically polyester - which prevents crimping or undulations that can lead to loss of performance in the finished laminate. The stitching also enables easier handling as the fabric remains intact even when cut. Straight, non-crimped fibers within a multiaxial fabric system allow very good resin impregnation and wet-out, perfect for Infusion and all Closed Molding processes. The stitching helps the diffusion of resin vertically through the layers (Z direction), thereby optimizing infusion rates.

4 Product Orientation-Axis Features Benefits Quadriaxials /±45 /9/±45 (QX) Optimized directional fiber content. Four-layer construction reduces the number of steps in lay-up. Reduced fabrication costs Multiaxial reinforcement. Quasi-isotropic properties. characteristics And end-use APPLicATiOn Product Orientation-Axis characteristics end-use Application Unidirectionals (L) 9 (T) Designed for applications requiring a high concentration of reinforcement in only one direction by placing continuous fibers in either a or 9 axis. Fibers are held in place by either interweaving a lightweight hot melt yarn to lock the unidirectional fibers in place, or by stitching the fibers in place using a stitch yarn. Great for demanding applications with a high aspect ratio (length to width ratio) such as wind blades, poles, and stringers and are also commonly used in FRP pipe and fittings for increased strength. Useful in applications where a discrete area requires additional strength or stiffness. Wrapping of existing structural components, such as columns and beams with Unidirectional Fabrics could also greatly increase the lifespan and performance of these critical load-bearing members. Biaxials ±45 Stitch-bonded composite reinforcement combining equal amounts of continuous fiber oriented in the +45 and -45 directions in a single fabric offering off-axis reinforcement without the need to rotate other materials on a bias. Conformability behavior can be adapted to part shape and processing requirements. Structural laminates including marine panels, wind blades, and recreational sporting equipment such as snowboards.

High performance structural laminates including boat hulls, truck and trailer panels, wind blades, recreational sporting equipment and bridge decks. Triaxials /±45 (TLX) ±45 /9 (TTX) Stitch-bonded, non-crimp, composite reinforcements combining either a warp () or weft (9) ply with double bias (±45 ) plies into a single multi-axial fabric. For applications requiring a combination of axial and off-axis reinforcement including wind blades, boat hulls, storage tanks, trailer panels, and pultruded profiles such as bridge decks. Quadriaxials /±45 /9/±45 (QX) Stitch-bonded, non-crimp, composite reinforcement combining warp (), weft (9), and double bias (±45 ) plies into a single multiaxial fabric. For applications requiring quasi-isotropic performance such as heavy structural laminates for boat hulls and decks, trailer panels, shipping containers, and pultruded profiles.
