Abstract:The paper studies compressibility and permeability of a CNT/CNF-grafted woven
carbon reinforcement. It is shown that the pressure needed to achieve the target fibre volume fraction of the perform increases drastically when CNT/CNF are present in the preform. This can lower the achievable fibre volume fraction for economical vacuum assisted light-RTM manufacturing and increase the pressure requirements in autoclave processing. The permeability of the preform is found to be non-affected by the presence of CNT/CNF.
