As manufacturer of carbon rims, ACTION COMPOSITES makes use of sophisticated braiding technology. The bicycle rims are produced automatically on the world’s largest radial braiding system with a diameter of nine meters. Braiding technology offers significant advantages over conventional manufacturing processes: the seamless processing of carbon fibres increases the rims’ strength, stability, and damage tolerance.
This high quality 29”-rim features reinforced nipple seats and massive rim flanges, which significantly increases the useful life. Moreover, the profile shape and the optimized fibre structure increase the rigidity of the braided carbon rim. Accurate feedback and a safe driving experience are the result of this design.
Using a combination of patented braiding technology and RTM (Resin Transfer Molding) that is unique in the bicycle sector, an extraordinarily robust and agile carbon rim has been developed. Thanks to precise manufacturing, it is perfect for being used in demanding terrain and withstands the extreme challenges in the MTB and e-bike sector.
C4R made by ACTION COMPOSITES is a reinforcement bar that consists of corrosion-resistant high-strength carbon fibers, which are embedded in high-temperature-resistant special epoxy resin.
In an industrial process, the bars are manufactured continuously with an optimized groove-helix design. In addition to the significantly higher tensile strength compared to reinforcing steel, C4R stands out by a significant mass saving of up to 80% compared to its steel equivalent. Moreover, the bond stress achieves top values, which were determined in a concrete pull-out procedure and are significantly higher than comparable fiber-reinforced reinforcement bars.
Through its durable and flexible characteristics Carbon concrete portrays a resource saving alternative to reinforced concrete by saving up to 50% of materials. The lightweight, as well as easy formability provide the basis for a large amount of design possibilities. Even extensive cage structures can be set up much better due to the smaller handling masses. The world’s first building with C4R carbon concrete is the CUBE at the TU Dresden.
Our reinforcement bars are available in different diameters, groove geometries and lengths. They stand out by featuring the following product properties:
