In order to meet the growing demand for carbon components and considering their sensitivity to impacts, stone chippings and crashes, 
jostec composites provides professional carbon repair. Providing end-to-end service from the analysis to the repair of visible and invisible 
damage we also offer non-destructive testing in  cooperation with a partner company.

- Repair of carbon components for biking, sailing, motorsports, fun sports, …
- restoration of full stability and strength
- non-destructive testing using pulsed thermography
- repainting of carbon components
- verifying the profitability of a repair job

We provide expert advice on an individual basis. Contact us.  Please send us photographs of the damaged part / spot 
or give  us a call in advance.

Different wall thicknesses on the frame as well as pores or damaged areas are displayed in different colors. The trend to use more and more CFK-based add-on parts for carbon bikes has acquired an almost threatening dimension. Safety-related parts such as the seat post or the fork are subject to bending stress. However, the main advantages of the CFK material come to bear mainly under tensile stress while bending forces should be avoided. In order to prevent notch effects, differences in wall thickness, air inclusions or other material faults from causing a part to fail, such parts should be examined through non-destructive testing. We carry out such tests in a quick and skilled manner. For this purpose the frames / add-on parts should be delivered in a disassembled state.

Prices for pulsed thermography: seat post€ 50.00; carbon fork € 75.00; carbon frame € 100.00 (net price without cost of transportation). Quotes for other combinations or individual components are provided upon request.

We do not pass any purchase recommendations as no brand is entirely free from damage.

Repair of an MTB carbon frame with a typical damage on the top tube caused by the handlebar / brake lever. Exposure of the damaged spot incl. delaminated carbon layers. First the damaged spot is sealed again with a non-compacted laminate in order to restore a closed frame (hollow body). Using a specifically selected epoxy resin and applying the ideal processing temperature we achieve partial hardening of this sealing layer which then gets fully hardened together with further structural layers in a fully automatic tempering oven under vacuum conditions and controlled heating. This ensures optimum binding of all layers of this two-phase process, resulting in maximum stiffness without any weight increase. To validate the reliability of the process we record the temperature, hardening and vacuum curves for the entire process.

Repair price (examples): dislocated derailleur hanger as of € 80.00 (net price) / damaged top tube € 240.00 (net price); quotes are always drawn up on an individual basis.
