Abstract: Wood fromtwovarieties of beetle-killed trees was used to fabricate wood–plastic composites. Loblolly pine and lodgepole pine beetle-killed trees were defibrated mechanically and thermomechanically, respectively, into fiber. Fiber and sawdust produced from the trees were modified with potassium methyl siliconate (PMS) and injection-molded into fiber/sawdust reinforced plastic composites. Modification of fiber and sawdust with PMS improved the compatibility between lignocellulosic materials and ethylene plastic in the composites, resulting in decreased water sorption, increased dimensional stability, and increased tolerance to morphological variations in the fiber and sawdust. Fiber-to-sawdust ratio and size of sawdust particles affected the time required for saturation with water, as well as dimensional stability.

Keywords: Wood-plastic composites; beetle-killed trees; wood flour; potassium methyl siliconate; water sorption; morphology
