The proof of concept is extended to CFRC panels where nanocomposite phenoxy films are prepositioned
between every odd carbon layer of the preform. Carbon nanotubes are filtered by the carbon fabrics,
which limits their full diffusion and that of phenoxy through the preform. This has negative consequences
on fracture toughness (GIc). For nanoclay, GIc is rather slightly improved although the origin is not fully
clear.
