Available in PDF, EPUB and Kindle. Book excerpt: The changes in properties of particleboard that result from changes in moisture content should be determined to avoid possible problems related to linear expansion and thickness swelling and to loss in load-carrying capacity and stiffness. In this report the physical and mechanical properties are determined for five commercial particleboards manufactured primarily from planer shavings and for a board made at the Forest Products Laboratory from random-width Douglas-fir flaxes, 1 inch long and 0.015 inch thick. All were conditioned at humidity exposures between ovendry and 90 % relative humidity. (Modified author abstract).
