Abstract: High-temperature foams are produced and used in the construction of aeroplanes, ships and rail and other vehicles. In particular, the foams are further processed into sandwich materials by joining with two outer layers. To this end, a novel process is used for producing high-temperature foams (HT foams) which are particularly suitable for producing such sandwich components for lightweight construction. This process achieves an improvement in the processability of the HT foams produced and a weight reduction of the sandwich materials. The HT foams are furthermore rigid particle foams which are markedly more economic to produce than rigid block foams. In particular, a reduction is brought about in resin absorption in fibre composite processes through a process-related optimization of the surface constitution.
