Wood-polymer composites (WPC) are materials in which wood is impregnated with monomers that are then polymerised in the wood to tailor the material for special applications. The resulting properties of these materials, from lightness and enhanced mechanical properties to greater sustainability, has meant a growing number of applications in such areas as building, construction and automotive engineering. This important book reviews the manufacture of wood-polymer composites, how their properties can be assessed and improved and their range of uses. After an introductory chapter, the book reviews key aspects of manufacture, including raw materials, manufacturing technologies and interactions between wood and synthetic polymers. Building on this foundation, the following group of chapters discusses mechanical and other properties such as durability, creep behaviour and processing performance. The book concludes by looking at orientated wood-polymer composites, wood-polymer composite foams, at ways of assessing performance and at the range of current and future applications. With its distinguished editors and international team of contributors, Wood-polymer composites is a valuable reference for all those using and studying these important materials. Provides a comprehensive survey of major new developments in wood-polymer composites Reviews the key aspects of manufacture, including raw materials and manufacturing technologies Discusses properties such as durability, creep behaviour and processing performance

Wood-plastic composite (WPC) is a non-recyclable composite material lumber or timber made of recycled plastic and wood wastes which has become one of the most dynamic sectors of the plastics industry in this decade. It is used in numerous applications, such as, outdoor deck floors, railings, fences, landscaping timbers, park benches, window and door frames. This book starts with a brief glimpse at the basic structures and properties of WPCs. Aspects such as surface treatment, machinery used and testing types of WPCs are also covered. The following chapters of the book give a view of foam technology, flame retardant properties and colour retardant properties of WPCs. The way morphology affects or controls the physical and mechanical behaviours of the finished materials is discussed. Finally, the authors give an overview of the applications of wood-plastic composites in daily life. The book may serve as a source book for scientists wishing to work in this field.
Wood plastic composite (WPC) is a term which refers to a composite containing wood in any form, combined with either thermoplastics (which can be re-melted) or thermoset plastics (which cannot be re-melted once set).

Wood plastic composite (WPC) is a term which refers to a composite containing wood in any form, combined with either thermoplastics (which can be re-melted) or thermoset plastics (which cannot be re-melted once set). Thermoplastics include polyethylene and polypropylene which are used in numerous non-structural applications, such as bottles and containers. Thermoset plastics are formed from resins such as polyester and epoxy. Solid recycled plastic lumber (RPL), which is usually made from waste plastics without any wood or fibre element, also competes in this non-structural role. This Digest describes the manufacture of several types of WPC and their strength, stiffness and durability. Although their strength is low in comparison with timber, WPCs have been used for decking and bridges. Their properties are compared with those of fibre reinforced polymers (FRPs).
At any rate, effects of lubricants with or without coupling agents in WPC are still largely unpredictable and mainly empirical. Nonmetal lubricants do not increase a chance for covalent bonds formation between coupling agents and wood ...

A comprehensive, practical guide to wood-plastic composites and their properties This is the first book that presents an overview of the main principles underlying the composition of wood-plastic composite (WPC) materials and their performance in the real world. Focusing on the characteristics of WPC materials rather than their manufacture, this guide bridges the gap between laboratory-based research and testing and the properties WPC materials exhibit when they're used in decks, railing systems, fences, and other common applications. Complete with practical examples and case studies, this guide: Describes compositions of WPC materials, including thermoplastics, cellulose fiber, minerals, additives, and their properties Covers mechanical properties, microbial resistance, water absorption, flammability, slip resistance, thermal expansion-contraction, sensitivity to oxidation and solar radiation, and rheological properties of hot melts of WPC Covers subjects that determine esthetics, properties, performance, and durability of wood-plastic composite products Includes comparisons of different ASTM methods and procedures that apply to specific properties This is a comprehensive, hands-on reference for scientists, engineers, and researchers working with wood-plastic composites in plastics and polymers, materials science, microbiology, rheology, plastic technology, and chemical engineering, as well as an outstanding text for graduate students in these disciplines. It's also an excellent resource for suppliers and WPC manufacturers, and an accessible guide for developers, homebuilders, and landscape architects who want to know more about wood-plastic composites and their performance in the real world.
When the raw materials are recycled and waste material from various sources there can be problems with consistency and contamination. This is linked to the lack of standards for these manufactured composites.

Wood and polymers are working together to bring new performance properties previously unavailable. Composites of wood and polyethylene, polypropylene, or polyvinylchloride and plastic lumber are a hot topic in building products today. The automotive market is another pioneer for these products. Beyond these two established markets, a myriad of industrial and consumer uses represent major emerging outlets for wood composites. Heightened demand for these products is driven by greater durability, lower maintenance, lighter weight, and lower cost across all major applications. New compounding technologies allow for the thinner profiles needed for such uses as window profiles, expanding potential use of composites beyond the thick profiles used for decking. This information paper briefly covers the content and manufacture of WPCs and their benefits and disadvantages from a market point of view. When the raw materials are recycled and waste material from various sources there can be problems with consistency and contamination. This is linked to the lack of standards for these manufactured composites. However, where the raw materials are of good quality, the composites have more consistent properties than natural wood and offer a lower whole life cost because of reduced maintenance requirements.
Natural fibres are promising reinforcement to be used in thermoplastic composites due to their low weight and cost. The major usage of plastic composites is in transportation followed by the combined usage in marine and corrosive environments. However, the stability of wood plastic composite in corrosion and marine environment is not well understood. Manufacturers mostly rely upon some limited laboratory tests whose methodologies are useful for simulations but not for predicting product's service properties. An investigation has been carried out to assess the properties of rubber wood fibre reinforced polypropylene composites; and environment stability of these composites has been studied at three different temperatures. ----- Nafish Sarwar Islam.
