This technology is based on the concept of the leaf-veins, rigidifying a surface with minimum weight. Instead of the nervures we use so called ribs made with flax fibres to reinforce thin-walled structures, resulting in a “pseudo mini sandwich”, since no core material is involved.
High relevance due to less weight & less cost
The main effect of the powerRibs is that they triple the flexural stiffness of thin-walled structures without adding weight. Thus, cost and weight can be reduced when making composite parts, and damping properties can be increased by up to 250 %.
For any given composite part, a large part of the synthetic fibres – such as glass or carbon – can be replaced with this novel material, increasing the part’s bio-based material content. This effect adds up to the powerRibs structure’s lower weight, outperforming any given material in terms of sustainability.
These ribs are easily combined with any type of base fabrics, such as natural fibre- (NF), glass fibre- (GF) or carbon fibre (CF) reinforcements.
The powerRibs fabrics can easily be processed with the common vacuum molding techniques. Furthermore, Bcomp Ltd. has partnered with processing technology partners, to develop concepts for the mass production of powerRibs parts.
Depending on the final application, two processing technologies are currently available: a sophisticated thermoplastic version for interior automotive parts and luggage shells on one hand side, and a thermoset-based version for the production of automotive body- and space parts on the other hand side.
We have compiled a significant amount of data on the material‘s mechanical properties, such as static- and dynamic behavior, thermo-mechanical characteristics and processing parameters of various production technologies. Contact one of our engineers for technical support.
