To meet the design goal for minimum radiation length, thus strongly reducing material wall thicknesses and mass of next-generation cryostats for detector magnets and calorimeter cryostats, Carbon Fibre Reinforced Plastic (CFRP) will be explored and compared to advanced metal and hybrid honeycomb structures. 

Cryostats for super-cold liquid fluids are still the purview of metals, but in order to decrease the thickness and material budget, lightweight and strong composite materials should be considered. Developments in this field could also be beneficial for the aerospace industry aiming to reduce the weight of tankers while ensuring their reliability. Given the great variety of approaches and materials under development, the future of these applications looks promising. The application in HEP detector should profit from this development and investigate how to tailor these new processes and materials for detector applications.
