  • The wood fibers are obtained from waste materials generated by lumber manufacturers, which are then processed to produce a consistent reinforcing product. The use of these particles promotes the reclamation of wood waste that would otherwise be sent to landfills and ensures that no new trees are cut down to make the product. wood-plastic composites also reduce energy use, since they melt at lower temperatures than typical plastics. Perhaps most recognizable as decking& ...

WPCs are typically made using 30% to 60% wood filler or reinforcements. Most composites research at FPL has used wood flour as a filler in plastics. wood flour is made com- mercially by grinding postindustrial material, such as planer shavings, chips, and sawdust, into a fine, flour-like consistency. wood fiber, although& ...

  • one advantage over wood is the ability of the material to be molded to meet almost any desired shape. A WPC member can be bent and fixed to form strong arching curves. Another major selling point of these materials is their lack of need for paint. They are manufactured in a variety of colors, but are widely available in grays and earth tones. Despite up to 70 percent cellulose content (although 50/50 is more common), the mechanical behavior of WPCs is most similar to neat polymers.

  • However, for the third-most used plastic polyvinyl chloride (PVC) [11], only a few studies have focused on PVC composites formed with chemically modified bamboo particles [12 14]. PVC thermoplastic properties can be readily modified through addition of fillers and additives to enhance performance including flexibility, elasticity, and impact resistance [11]. Adding a natural material to PVC not only serves as composite filler but also reduces polymer use with a& ...


  • There are several polymers that meet this requirement, but the three most common polymers used in WPCs are polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). Differences in chemical properties lead into hindered coupling between the hydrophobic polymers and hydrophilic wood fibers, which can be improved by using compatibilizers, such as maleated polypropylene (MAPP) or silane coupling agents. However, even though the effects of coupling agents on the& ...
