Foams are commonly used as cores for sandwich structures to render their low density and desired mechanical performance. However, most of the core foams and the sandwich composites are currently made from plastics, which, after failure, become non-degradable waste. In BreadCell we build sandwich constructions based on pulp fibre foam cores. The density and mechanical properties of the foam and the sandwich structure are well controlled to be competitive to the commercial plastic products. The forest-based foams and sandwich structures can even be recycled after their failure. Take a look at a video about the BreadCell sandwich structures.
