as plastic/wood composites undergo degradation at high processing temperatures, it is important to select a suitable polymer matrix that can be melted and processed at relatively low temperatures. thermoplastic polymers are preferred, as they allow easy processing of plastic/wood composites.
composites can be natural or synthetic. wood, a natural composite, is a combination of cellulose or wood fibers and a substance called lignin. the fibers give wood its strength; lignin is the matrix or natural glue that binds and stabilizes them. other composites are synthetic man-made .
these types of composites cover a range of different material combinations. the most common type is polymer matrix composites, however, metal matrix composites, and ceramic matrix composites are also common, as are natural composites such as wood. composite types up 2: fibre reinforced compposites .
study on the pyrolytic behavior of wood-plastic composites using py-gc/ms. wood plastic composites it has been suggested by other researchers that polyolenic polymers could provide hydrogen during thermal co-processing with wood biomass and could lead to an increase in liquid production.
wood plastic composites the term 'wood-plastic composites' wpcs globally refers to wood as a proxy for fibrous materials of plant origin. it can be wood flour or sawdust, or agricultural plant residues, typically cut, milled, or ground, or other types of natural fibre, such as hemp, jute, and kenaf, commonly as a by-product of the respective industrial process as per global terminology.
not all plastics are composites. in fact, most plasticsthe ones used in toys, water bottles and other familiar itemsare not composites. theyre pure plastics. but many types of plastic can be reinforced to make them stronger. this combination of plastic and reinforcement can produce some of the strongest, most versatile materials for
wood particles predominately being a byproduct of sawmill and other wood-processing waste streams, and because much of the plastic is de-rived from consumer and industrial recycling efforts. wpcs offer great flexibility in the shapes and colors of the materi-als produced. materials usage can be also be reduced through the en-
