Pre-consolidated, multiaxial, thermoplastic composite structures

LANXESS reports that its subsidiary Bond-Laminate has begun production of pre-consolidated, continuous fiber-reinforced thermoplastic Tepex composite laminates that feature fiber layers oriented at almost any conceivable angle.

LANXESS (Cologne, Germany) reports that its subsidiary Bond-Laminate (Brilon, Germany) has begun production of pre-consolidated, continuous fiber-reinforced thermoplastic Tepex composite laminates that feature fiber layers oriented at almost any conceivable angle.

Until now, the continuous fibers in Tepex could only be aligned in the direction of or perpendicular to production (0° or 90°). This process innovation means the designer can use the differently oriented composite continuous fibers to react more specifically to the force transmission in the target component. Even quasi-isotropic constructions can now be fashioned using Tepex.

As in the past, Bond-Laminates says it 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 are said to help keep wastage to a minimum in almost all cases. 

Thanks to the continuous fibers’ high degree of orientation, LANXESS says 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. Bond-Laminates is targeting automotive applications with this material.
