纖維飽和點(英語:Fibre saturation point,簡稱F.S.P[1])是木材力學,尤其是木材乾燥中使用的一個術語,表示乾燥過程中僅殘留結合在細胞壁中的水,所有其他的水份(即自由水)已從細胞中去除。木材的進一步乾燥導致木質纖維的增強[2],通常伴隨著收縮。木材通常被乾燥到與大氣中的水分或相對濕度達到平衡的程度,並且由於這種變化,平衡水分也隨之變化。實驗發現,許多木材的纖維飽和點平均值約為26%。但不同物種的纖維飽和點平均值會有所不同[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 細胞壁 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]
