SGL Group will be presenting its full range of carbon fibres, textile products and prepregs to carbon fibre reinforced components (CFRPs) at Composites Europe, which runs from September 22-24, 2015 in Germany.

“For the first time, the company will present an isotropic non-woven prepreg (ICV prepreg) based on recycled carbon fibres combined with an epoxy resin,” a SGL press release informed.

“Due to a new manufacturing process that makes it possible to use recycled carbon fibres, this material possesses almost isotropic mechanical properties,” it said.

The ICV prepreg has an entirely new type of surface appearance and can be used in pressing processes as well as conventional autoclave processes.

“These characteristics make the material especially interesting as a means of opening up new applications with epoxy resin prepregs,” the company added.

SGL further added that the Sigrapreg prepregs can also be combined with new fast-hardening resin systems that are under development with a view to fulfill requirements of large-scale component production.

“These Snap-Cure resin systems combine excellent hardening times, good storage stability and adhesiveness of the pre-impregnated semi-finished products optimised for automated machining,” it informed.

SGL Group will be presenting long fibre-reinforced thermoplastics (LFRPs) for the first time and are available as both glass fibre-reinforced and carbon fibre-reinforced semi-finished products.

These can be used on the basis of various plastic types and enable significant benefits, such as short cycle times, weldability, good recyclability and ease of combination with other thermoplastic semi-finished products.

The new thermoplastic materials and their applications will be presented at the trade show using the example of a front end.

This is made from LFRP consisting of glass-fibre-reinforced polyamide (GF-PA6) in which unidirectional (UD) tapes and carbon fibre-based organic sheets are integrated directly in a manufacturing process.

Another innovative product on show is the Sigrapreg TowPreg, which has already been shown at JEC 2015 for the first time.

According to SGL, these pre-impregnated rovings made from carbon or glass fibres are especially suitable for challenging winding and lay-up processes thanks to their outstanding winding properties.

The products on display are completed by a transparent resin system for prepregs, which is used in particular for visible components, such as in the automotive industry.

“When used in conjunction with extremely high-quality Sigratex design fabric from SGL Group, this produces components with supreme surface quality and sophisticated visual appeal,” it observed. (AR)
