the coefficients ci thermal expansion of wood and wood products

Little data are available on the thermal expansion of natural solid wood, plywood, impreg, compreg, and papreg, and none on staypak, and hydro- lyzed wood, plastics and laminated sheets. Consequently, the studies here- in reported were

Thermal properties of wood Wood Products

Increasing the moisture in the wood also increases its thermal conductivity. As the temperature of wood decreases, its strength usually increases. The thermal expansion of wood in the direction of the grain is very little. In the radial and
