The Influence of Dry-Milled Wood Flour on The Physical ...

 · When wood flour with 5 wt% water content was milled for 2 and 4 h, the resulting wood flour was granular rather than fibrous; flocculation of the fine particles was observed for milling times exceeding 4 h. This morphological change in the wood flour reduced its influence on the physical properties of the composites, although some positive influences were observed on the molding properties of the composite, such as an increase in compound fluidity.

Strength properties of wood | Wood Products

The strength of wood increases as its density increases. When evaluating the density of wood, the level of moisture in which its mass and volume were measured must always be known. Most commonly the density of wood is given as dry air density, whereby the mass and volume of the wood are measured with its level of moisture at 15% (or 12%).
