纤维饱和点(英语:Fibre saturation point,简称F.S.P[1])是木材力学,尤其是木材干燥中使用的一个术语,表示干燥过程中仅残留结合在细胞壁中的水,所有其他的水分(即自由水)已从细胞中去除。木材的进一步干燥导致木质纤维的增强[2],通常伴随着收缩。木材通常被干燥到与大气中的水分或相对湿度达到平衡的程度,并且由于这种变化,平衡水分也随之变化。实验发现,许多木材的纤维饱和点平均值约为26%。但不同物种的纤维饱和点平均值会有所不同[3]

Fibre saturation point is a term used in wood mechanics and especially wood drying, to denote the point in the drying process at which only water bound in the 细胞壁 remains - all other water, called free water, having been removed from the cell cavities. Further drying of the wood results in strengthening of the wood fibres,[2] and is usually accompanied by shrinkage. Wood is normally dried to a point where it is in equilibrium with the atmospheric moisture content or relative humidity, and since this varies so does the equilibrium moisture content.

Laboratory testing has found the average FSP in many types of wood to be approximately 26%. Individual species may differ from the average.[3]
