Abstract

Wood-polymer composites (WPC) are among the green composites that are environmentally friendly and renewable. These innovative composites have attractive features such as light weight, low cost, biodegradable, suitable mechanical and physical properties. Typically, wood-polymer composites can be prepared by combining various types of thermoplastic and thermoset polymer matrices with flour of different wood species with common polymer processing methods such as extrusion, injection molding, and compression molding. The wood particles used in these composites are divided into two general categories: softwood and hardwood, each of which has its own structure and characteristics. Considering these advantages, wood-polymer composites are often recognized as an exciting alternative to polymers, conventional polymer composites and wood, and are increasingly used in the construction, automotive, transportation, home appliances, sports equipment and etc. By the way, in this review article, wood-polymer composites and its components are first introduced, and then the chemical structure and properties of different types of wood species are also investigated. In the following, the mechanical, thermal and water absorption properties of WPCs are discussed and finally their diverse and attractive applications are stated.
