5. Conclusions and Outlooks
- The investigations in solution have shown that CP with investigated carbon anodes up to 2200 mV versus NHE is possible
- The Carbon filaments within the Carbon textiles as CP anode have not been destroyed up to the investigated potentials up to 2200 mV versus NHE.
- With SBR impregnated samples, the impregnation is destroyed right from the start during polarization.
- The sizing is destroyed at a potential of about 900 mV versus NHE.
- Epoxy impregnation started to destroy between 1050 and 1150 mV versus NHE.
