Investigations on Epoxy-Carbamate Foams Modified with Different Flame Retardants for High-Performance Applications

In transport sectors such as aviation, automotive and railway, materials combining a high lightweight potential with high flame retardant properties are in demand. Polymeric foams are suitable materials as they are lightweight, but often have high flammability. This study focuses on the influence of...
