Abstract
The recycling of cross-member composite (CMC) parts was studied using partial decrosslinking of the polyurethane (PUR) composite matrix by catalyzed glycolysis. The decrosslinked material, containing reactive OH and NH2 groups, was reacted with polymeric isocyanate in a molding operation to form a new composite product. In order to make the process economically feasible the smallest amounts of reactants (glycol, catalyst, isocyanate) were used in the process. The results of the laboratory study were verified in semi-pilot plant runs. The economic analysis showed that the process is feasible.
