BASF says that its new polyethersulfone Ultrason E material makes it easier to make sandwich structures for airplane interiors.
The same material can reportedly be processed into different components of the sandwich structure in a single tool, helping reduce cycle times and manufacturing costs.
The sandwich consists of a foam core and carbon fiber laminates made of Ultrason E, and if required, the thermoformed foam core with cover layers can then be overmolded with carbon-fiber reinforced Ultrason E 2010 C6 to incorporate reinforcements, structures or additional functional elements into the sandwich. The combination of 30% carbon fibers with the amorphous high-temperature plastic can improve mechanical properties for the light foam sandwich over a temperature range of -100 to +200°C.
The material, has a limiting oxygen index of 38 (according to ASTM D 2863) and meets the requirements for commercial aircraft with regard to combustibility and heat release without the addition of flame retardants.
