There are numerous possible combinations of cores and outer layers. Depending on the application, a glass, aramid or carbon textile, for example, is used for the cover layers. This can be a woven fabric, non-crimp fabric or even a nonwoven fabric from TENOWO. Depending on the application of the finished sandwich panel, the core materials vary from PU or PET foam, to honeycomb core structures made of paper or wood, to wool.
The latest development from TENOWO describes volume nonwovens as "spacer material". These are more attractively priced than foams, for example, and more sustainable due to the use of recycled fibers.
