1.. IntroductionWood–plastic composites (WPC) are widely used in USA, the most common type of such panels are produced by mixing wood flour and plastics to produce a material that can be processed similar to 100% plastic-based products , , , .
Abstract. In order for wood to be used to make composite products, feedstock originating from trees and logs must first be obtained, sometimes as a by-product of other primary wood processing operations.
PROPERTIES OF WOOD AND STRUCTURAL WOOD PRODUCTS 3.1 INTRODUCTION Wood differs from other construction materials because it is produced in a living tree.
Wood Composites - UEF Electronic Publications. Jun 10, 2016 . 2 Wood-plastic composites. By definition, composite materials are formed by combining two or more constituent materials that have substantially different chemical or physical properties (Callister 2005).
Our wood composite has exceptional qualities of use due to its unique formulation. Composed mainly of wood, the Silvadec composite is a unique high-quality color-impregnated material composed of 2/3 wood flour and 1/3 polyethylene with an exclusive reconstitution in the form of fibers for greater durability.
Polyurethane-based binders, typically used both with wood and rubber, are used in composite wood products to permanently glue organic materials into oriented strand board, medium-density fiberboard, long strand lumber, and even strawboard and particleboard.

Engineered wood, also called composite wood, man-made wood, or manufactured board, includes a range of derivative wood products which are manufactured by binding or fixing the strands, particles, fibres, or veneers or boards of wood, together with adhesives, or other methods of fixation to form composite materials.
We say wood is anisotropic, which means a lump of wood has different properties in different directions. Photo: Wood is a traditional building material, as popular today as ever. Because wood is anisotropic, natural wooden beams work better as vertical posts (where they are in compression) than horizontal beams (where they are in tension).
Because wood properties vary among species, between trees of the same species, and between pieces from the same tree, wood in the solid form cannot match wood in the comminuted and reconstituted form in providing materials with a wide range
made from composite wood products that were manufactured prior to the Phase 1 or Phase 2 effective dates. After the sell-through period, finished goods containing HWPW, PB, or MDF, must
their physical and mechanical properties as well as appearance of such products to have a strong market share in wood composite panel industry. There are several ways to improve
