Multifunctional nanoreinforced composites

Details

Laminated composite materials such as Carbon Fiber Reinforced Plastic (CFRP) are a well-know class of composite materials. The latest wide body airliners such as Boeing’s 787 and Airbus A350 XWB are primarily constructed out of composites materials including critical structural components such as the fuselage, floor beams and wings. 
In order to maximize fuel efficiency, the weight and components of the aircraft must be reduced even further. The next generation of aerospace materials should have additional properties that would allow them to replace several layers of monofunctional materials at once.
Carbon based nanomaterials, metallic nanoparticles along with a new generation of conductive polymers are some of the promising fillers that can be added to composite materials or engineering plastics to tailor their material properties such as electrical and thermal conductivity. These fillers can have a profound effect even at very low concentration. It is therefore necessary a complete understanding of the mechanisms in which these fillers change the material’s properties
We design and process nano reinforced materials and investigate their behavior by several characterization techniques including microscopy, x-ray tomography, mechanical analysis, thermal analysis, electrical conductivity measurements and coupled electromechanical analysis.
The final target is to predict the influence of the formulation and the process on the final macroscopic properties so we can provide tools as a guide for their practical design. This requires advanced modeling and simulation strategies that are also developed by the COHMAS team.
