The term wood-plastic composites refers to any number of composites that contain wood (of any form) and either thermoset or thermoplastic polymers. Thermosets or thermoset polymers are plastics that, once cured, cannot be remelted by heating.
Carbon fiber composites are now quite common in commercial and military aviation. The Boeing 787 and Airbus A350 XWB have roughly 50% of their structure from composite materials. Carbon fiber materials are also common in helicopter systems, rocket motors, satellite systems, and turbine engines.
MatWeb has entries for well over 8000 polymers, including both thermoplastics and thermosets, which have been reinforced through the addition of glass fiber, carbon fiber, aramid fiber, wood, or mineral reinforcements.
mechanical performance than glass, the balance of properties that wood fibers yield, along with other advantages such as lower density, aesthetics, and low abrasiveness during processing offer advantages in some applications.

This article gives an overview of the recent literature, covering all aspects of WPC materials and their performance as of today. It focuses on their compositions, that is, thermoplastics and thermosets, wood fiber types, and additives.
Thermosets find wide ranging applications in the chopped fiber composites form particularly when a premixed or moulding compound with fibers of specific quality and aspect ratio happens to be starting material as in epoxy, polymer and phenolic polyamide resins.
The term WPCs relates to any composites that contain plant (including wood and non-wood) fibers and thermosets or thermoplastics. Thermosets are plastics that, once cured, cannot be melted by repeating.
This increases the mechanical properties and is technically considered a fiber reinforced composite, however, the strength is not nearly as comparable to continuous fiber reinforced composites. In general, FRP composites refers to the use of reinforcing fibers with a length of 1/4" or greater.
High-performance composites derive their structural properties from continuous, oriented, high-strength fiber reinforcement — most commonly carbon, aramid or glass — in a matrix that promotes processability and enhances mechanical properties, such as stiffness and chemical resistance.
The predominant applications for phenol-formaldehyde thermosets 2 are as adhesives for plywood and as binders for similar wood products: oriented strandboard, hardboard, particle board, and molded wood products. For these applications, phenolic resins offer low cost and good compatibility with wood fiber.
Composites derive their properties from the combination of a fiber and resin matrix, which can be accomplished with one of several fabrication types, which will be covered in next month's newsletter. The Boeing 787 was the first commercial aircraft to use composites extensively in structural components.
Given these properties, combined with an inexpensive source of fibres, wood fibre–plastic composites could theoretically offer desirable specific strengths and modulus at a low cost. Wood fibres including paper fibre, wood flour and wood are a good natural choice for synthetic fibres.
Abstract. The effects of size and concentration of wood particles on the properties of composites, obtained by extrusion, were evaluated based on polystyrene and wood particles from Eucalyptus globulus Labill.
This paper represents a review on microcellular wood fiber reinforced polymer composites obtained by different processes (batch, injection molding, extrusion, and compression molding process) and.

The term “wood-plastic composites” refers to any number of composites that contain wood (of any form) and either thermoset or thermoplastic polymers. Thermosets or thermoset polymers are plastics
high wood fiber content composites directly to final shape without the need for milling or further for ming. Strandex has continued to license its evolving technology.
Thermosets are an attractive alternative to metals and thermoplastics due to its exceptional physical properties and surface appearance. Thermoset composites remain stable in high and dynamic temperature applications, a beneficial quality in the rapidly shifting world of manufacturing.
The coconut fiber-filled polyvinyl chloride/acrylonitrile styrene acrylate blends had the higher impact strength and thermal properties than that of the wood-PVC composites when fiber content was not varied.
