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.
Lanxess has achieved a process innovation in the production of continuous fiber-reinforced thermoplastic Tepex composites.
The subsidiary company Bond-Laminates, which manufactures these composites, is now able to continuously series-produce large semi-finished composite products in which the continuous fiber layers can be oriented at almost any conceivable angle.Until now, the continuous fibers in Tepex could only be lined up in the direction of production or perpendicular to it (0 degrees or 90 degrees). This process innovation means the designer can use the differently oriented composite continuous fibers to help him react more specifically to the force transmission in the target component. Even quasi-isotropic constructions can now be fashioned using Tepex.These multiaxial Tepex semi-finished products are fully impregnated and consolidated. Despite being formable to quite extreme angles, their impregnation means the fibers are unlikely to slip. As in the past, Bond-Laminates will consult closely with the customer regarding cutting the semi-finished products into pre-contoured profiles for forming and overmolding or compressing. Special nesting programs help keep wastage to a minimum in almost all cases.Thanks to the continuous fibers’ high degree of orientation, the individual fiber layers demonstrate almost unidirectional properties. The stiffness and strength of the individual layers based on polyamide 6 and continuous glass fibers are 37 GPa and 780 MPa respectively in the direction of the fibers.Their mechanical set of properties, which can be tailored to meet specific requirements, makes multiaxial Tepex semi-finished products the perfect material for manufacturing high-strength structural components and semi-structural components for automobiles in particular.More information: www.lanxess.com
