Sustainable lightweighting for large scale mobility

Cut weight and plastic with powerRibs™

There is an ongoing revolution towards cleaner mobility for the future. Bcomp’s solutions for sustainable lightweighting with thermoplastic powerRibs™ can cut weight by up to 50% and reduce plastic by up to 70% in interior panels. Thereby both the impact of materials used, and fuel consumption can be reduced. The solution is cost-efficient and can be seamlessly integrated into high-speed production lines. ampliTex™ technical fabrics enable novel design options, creating a functional and visual layer in one.

Bcomp’s solution for sustainable lightweighting in interior panels with thermoplastic powerRibs™ for large scale production won the JEC Future of Composites in Transportation 2018 Innovation Award in the “sustainability” category together with Persico.

Implementation projects are ongoing with multiple OEMs for interiors in serial production models.

In 2018, the solution was used to reinforce recycled ocean plastic in the Volvo Cars Recycled Plastics Demonstrator Vehicle presented in connection to the Volvo Ocean Race.

In 2020, Polestar announced a partnership with Bcomp for the development of more sustainable interior panels in future production models, as well as for visual panels in the Polestar Precept.

A few examples

powerRibs™  in Volvo Cars Recycled Plastics Demonstrator Vehicle

For the release of Volvo Cars recycled plastics demonstrator XC 60 vehicle, Bcomp’s natural fibre reinforcement technology - powerRibs™ - is combined with recycled ocean plastic to form a novel composite material. This enables the use of ocean plastic in semi structural automotive interior parts, and simultaneously cuts up to 50% of weight compared to standard parts.

Bcomp wins JEC Innovation Award with tooling expert Persico Automotive 

Bcomp and Persico Automotive received the JEC Future of Composites in Transportation 2018 Innovation Award for the production technology that enables the use of high-performance powerRibs™ natural fibre reinforcements on an industrial scale.

Award-winning production technology

All Cases


powerRibs™ and ampliTex™ are made from flax fibres that grow naturally in Europe without competing with food crops. By optimising the properties of the fibres mechanically and through fabric architecture, less material is used. At the end of their life, parts can be ground down into a new base material, or used for thermal energy recovery without residual waste in the standard waste management system. ​


Thermoplastic parts are made using one-step back-injection, which compression moulds powerRibs™ with a base layer NFPP fleece, decorative surface layer, attachment points and punching in the same step. With the award-winning employment of a soft silicone layer on the b-side in the compression moulding tool, the full stiffening potential of the powerRibs™ preform is reached and maintained. Our team of specialised engineers support clients all the way to their finalised part.

Novel design options

The powerRibs™ + NFPP solution can be easily wrapped in any traditional coverstock material, while Bcomp also offers a range of ampliTex™ technical fabrics for additional stiffness and novel design options, that can be integrated in the production to complete the solution.
