Composites from southern pine juvenile wood. Part 3. Juvenile and mature wood furnish mixtures

Abstract

Composite panelsmade from mixtures ofmature andjuvenile southern pine (Pinus taeda L.) were evaluated for initial mechanical properties and dimensional stability. The effect that the proportion of juvenile wood had on panel properties was analyzed by regression and rule-of-mixtures models. The mixed furnish data: 1) highlighted the degree to which juvenile wood types can affect specific panel properties; 2) substantiated significant and non-significant differences found in parts 1 and 2 ofthe study for homogeneous panels; and 3) showed the rule-of-mixtures to be a good model for property changes due to changes in the proportion of juvenile wood in the furnish.
