WebFiber saturation point (FSP) moisture content when cells are completely saturated with bound water but no free water (water inside cell cavities doesnt affect shrinkage) inside cell cavities FSP = 21-32% Above FSP = changes affect only wet weight Below FSP = small changes strongly affect all physical and mechanical properties shrinkage WebApr 21, 2024 · Traditionally, water in wood exists in two main forms: as bound water within the cell wall, and as free water in the cell lumens. The fiber saturation point (FSP) is primarily used to distinguish these forms of water. The term fiber saturation point was originally applied to wood by Tiemann ( 1906 ).
WebWood that is dried below what is termed the fiber saturation point (about 30% water content for oak wood at 20 °C) undergoes shrinkage. The degree of shrinkage varies along the different dimensions of the wood, with radial and tangential shrinkage being much greater than longitudinal shrinkage. Webpoint. The fiber saturation point of wood averages about 30 percent moisture content. The fiber saturation point also is considered as that moisture content below which the …
