Sustainable lightweighting business, Bcomp (Fribourg, Switzerland), is now supplying its superior-effectiveness natural fiber technologies to HWA AG (Affalterbach, Germany) — development partner of Mercedes-AMG (Baden-Württemberg, Germany) — for the new entrance bumpers on Mercedes-AMG GT4 race automobiles. Set to be phased in more than the coming weeks, Bcomp’s bodywork alternatives will give a sustainable different to the GT4’s existing carbon fiber panels, supplying equivalent mechanical general performance in stiffness and pounds and enhancing safety.

The new bumper makes use of Bcomp’s effectively-acknowledged ampliTex and powerRibs technologies, which harness the purely natural benefits of flax fiber. The powerRibs reinforcement grid takes advantage of the large unique bending stiffness of flax to establish up peak efficiently, Bcomp details out, boosting the flexural stiffness of thin-walled shell aspects noticeably. The new bumpers are also safer in the celebration of a crash or collision and lessen the possibility of punctures, with powerRibs confining the destruction zone and reducing debris.

“Development coincided with the height of the pandemic, and it was complicated at instances,” Christian Fischer, CEO and co-founder of Bcomp, feedback. “In reality, our initial bumper build, structure fitting, optimizations and revisions were all reached throughout the pandemic — a testimony to the tough work and persistence of all concerned. It has been a pleasure to function with the HWA team and we look forward to investigating even further applications in race and higher-effectiveness street cars and trucks.”

A full sustainability investigation concluded that the new bumper available a complete content emission reduction of 90% when compared to the carbon fiber part as properly as an 85% reduction of CO2 emissions from cradle-to-gate, thinking of all output actions from raw product to final part. Bcomp’s elements not only decreased the part’s carbon price tag, but they also launched the selection of thermal strength recovery. Considering that the new bumper is full pure fiber, it is claimed it can recover somewhere around 80% of the electrical power saved in the component into renewable energy, resulting in a process with no hazardous carbon squander or sections that need to have to go into landfill.

Reverse-engineered from HWA’s original, the organic fiber bumper’s style has been collaboratively optimized more than the past 12 months. To assure that the bumper fulfilled all racing rules and requirements, the HWA crew performed intensive mechanical tests and validation. On the HWA testbench, the stiffness of the finish frontend of the Mercedes-AMG GT4 was calculated, simulating the aerodynamic drag and entrance diffusor downforce. The exams had been conducted with a carbon fiber bumper as benchmark and later on with the all-natural fiber bumper, validating that the freshly designed component performs on the similar large-overall performance degree.

Furthermore, portion of the undertaking was to validate the HWA inhouse paint procedures with ampliTex and powerRibs, optimizing the A-area high-quality of the aspect up to a stage that meets the top quality standards of HWA and Mercedes-AMG motorsport. Production of the outdated carbon fiber bumpers has now ceased, and all buyer groups will obtain the new Bcomp edition with their upcoming orders.

Bcomp claims its technologies are now used in 16 racing collection all-around the world, but their applications are not restricted to motorsport. From automotive interior panels and bodywork to luxurious yachting and the European Room Agency’s (ESA’s) natural fiber satellite panels, Bcomp’s systems are relied upon where ever fat, stiffness and sustainability are crucial. With the GT4 vehicles closely primarily based on their street-going counterparts, these racing jobs open up up chances for potential large-general performance road programs. 

“The subject matter of sustainability performs a major role in our enterprise. A number of awards for our initiatives in the location of environmental safety are evidence of this,” Anne Mink, manager technological development, HWA AG, provides. “Part of our sustainability thought is to appraise and improve the solution lifetime cycle with regard to environmental factors as early as in the product improvement stage. Furthermore, it is our aspiration to consistently adapt our very long-standing engineering know-how to present-day environmental needs in get to be in a position to offer our clients sustainable items at the greatest technological level. In Bcomp, we have bought a advancement lover with in depth knowledge in sustainable supplies. The result of our cooperation exhibits that technologically equal factors can be designed from choice materials.”
