Comprehensive review of wood plastic composites

Wood-plastic composites (Wood-Plastic Composite, WPC) is the name given to an engineered composite that includes at least two components Is. The first component of this composite is wood powder (the type of wood must be carefully selected for each feature and color) and the second component includes a wide range of polymers (including thermoplastic/thermoset polymers). The combination of these two components along with additives Another variety is used to make wood-polymer composite materials. The term wood-plastic is usually used instead of wood-polymer composites. The first wood-plastic composites were obtained almost a hundred years ago by combining wood powder with phenol-formaldehyde resins and were used in the manufacture of car gear shift knobs. On the other hand, the first reference of wood-plastic composites based on thermoplastic polymers dates back almost 60 years ago and from the combination of wood sawdust with them in the extrusion process. In this series of articles, we will try to look at things like the raw materials used to make wood-plastic composites, the additives used in them, a look at the interactions between wood and the synthetic polymers used, the technologies used in their manufacture, their mechanical properties, resistance and Their durability in environmental conditions, their creep and damage behavior, the efficiency of the extrusion production process in their production, arranged composites and their related materials, the improvement of wood-plastic composites products, … as well as their market and future course.
