The deformability of a textile fabric (as received, or with in-situ grown carbon nano-fibres, or with a thermal treatment) is studied experimentally using bending, compression, in-plane shear, and friction. These tests reveal that the in-situ grown carbon nano-fibres can significantly deteriorate the fabric deformability, except for a low mass fraction. Therefore, the optimal mass fraction should be chosen for a particular production case, to obtain a compromise between improved strength of a composite part (expected to increase after the nano-fibre growth) and decreased deformability of the preform.
