The Porsche 718 Cayman GT4 Clubsport MR tackled this 12 months‘s Nürburgring 24-hour race that includes a sustainable innovation: an entire physique package made from natural-fiber composite supplies.

At this 12 months’s Nürburgring 24-hour race, the workforce 4 Motors joined forces with Challenge 1 Motorsport to current a sustainable innovation on the racetrack that might change the manufacturing of automotive physique components sooner or later: Fitted with a natural-fiber composite materials physique package and powered by a 3.8-liter flat-six engine producing 313 kW (425 PS), the 718 Cayman GT4 MR took up the Nürburgring 24-hour race sporting the beginning quantity 420.

Since early 2019, Porsche manufactured the 2 doorways and the rear wing of the small sequence racing car out of a natural-fiber combine, sourced primarily from renewable uncooked supplies. Now for the primary time, the entrance and rear aprons, the entrance spoiler, entrance and rear lids in addition to the mudguards and diffuser together with the aerodynamic fins are additionally made from this regenerative materials.

These supplies exchange the steel and plastic injection molded elements of the manufacturing sports activities automotive. When it comes to weight and stiffness, the recyclable natural-fiber composite supplies of non-structural elements share properties much like carbon-fiber composites (CFRP) and meet the identical excessive security and high quality requirements. Pure-fiber composites will be manufactured extra economically and with much less vitality.

Farmed flax fibers function the idea of the sustainable natural-fiber composite materials — with out conflicting with meals crops. This improvement started in 2016 with collaboration between Porsche, the Federal Ministry of Meals and Agriculture (BMEL), the Fraunhofer WKI, and the Swiss firm Bcomp.

For the doorways, mild balsa wooden serves because the core of the composite materials. The sandwich building correlates to the well-known resin switch molding (RTM) course of used within the manufacturing of carbon-fiber elements. Against this, for the rear wing, layers are impregnated with epoxy resin then baked in an autoclave. The newly added elements made from natural-fiber bolstered plastic are created utilizing a vacuum infusion course of and include Bcomp’s proprietary powerRibs™ know-how to satisfy stiffness necessities.

Supplies of various thicknesses and fiber orientations make sure the exact adjustment to particular functions and cargo eventualities. Pure-fiber composite supplies are notably suited to areas that aren’t or solely partially a part of the car construction. Furthermore, the damping of vibrations improves fivefold and, within the case of an accident, splinter into bigger and fewer sharp items.

If the evaluation of the check outing on the endurance traditional goes effectively, it’s doubtless that Manthey-Racing will provide the components package to prospects.
