Premium Material Solutions N Nano-toughened carbon fibers composite materials by SAATI Group ( SEAL S.p.A.), a partner of Nanoledge. D. Mazzuccoa, D. Squizzatoa, S. Mantovania e P. Canonicob Introduction In the last few years words such as nanotechnologies and nanometric materials have taken place in common discussions in many different areas of science, technology and industry. Composite materials trade has only recently turned its attention, but with growing interest, towards these innovations: properties of materials can change radically when zooming from common dimension to microscopic dimension. This behavior is still enigmatic and addresses to some topics that are not easy to translate in intuitive concepts; however they often turn into extraordinary features that can be exploited to create brand new materials, with novel attributes, or modifying and enhancing already know materials. Carbon fibers composite materials industry, which works in a discipline where the research of high performance is at a very high level, looks with interest in the direction of newborn products that the market of nanomaterials makes available, in order to offer solutions in a process of continuous research and development. SEAL is a company that operates in the area of advanced composite materials and personal protection systems, that’s why has focused its efforts in the research and a SEAL S.p.A. b SAATI Group S.p.A. Premium Material Solutions N development of carbon fibers composite materials with high toughness: fracture mechanics of carbon composite materials are usually quite complex because of the anisotropy and disomogeneity of the material and they include both intralaminar damage (rupture of the fiber) and interlaminar fracture (delamination). These materials are particularly fragile to delamination fracture (due to the lack of reinforcement trough the thickness), t
