During these years, AS developed an outstanding engineering capability for the design and prototyping of both aeronautical and naval platforms, including their components. This process is supported by a large computing power and specialized software. We own different international patents and we are able to customize our proprietary nano-structured composite materials for extreme tasks. Three families of proprietary materials (High Temperature Shielding and Fireproof, Electro Magnetic Waves Absorbing and Shielding, Sound-absorbing) are fully characterized, tested and already certified and used by major international high-tech companies. AS has expertise in the manufacturing of very high quality components made of traditional composite materials, such as to be chosen by important defense groups as a supplier of key parts.
