Developing tools to assess mechanical properties of wood cell walls
Snapshot: Nanoindentation is a tool capable of probing mechanical properties at the sub-micrometer level, such as in wood cell walls, individual components in a wood-based composite, coatings, adhesive bondlines, etc. However, conventional nanoindentation methods are often not applicable and provide qualitative information at best. Therefore, reserachers developed advanced nanoindentation methods to increase the value of nanoindentation in understanding wood properties and developing advanced composites.
