Plastic lumber - Wikipedia

plastic lumber (PL) is a plastic form of lumber (timber) made of virgin or recycled plastic It is made of 100% plastic, compared with wood-plastic composites or rot-resistant wood. Unlike wood-plastic composite lumber, plastic lumber is 100% recyclable after its original intended use. Use in load-bearing structures requires different considerations from wood. plastic lumber can present issues with fire

Critical Issues in Extrusion Foaming of Plastic/ Woodfiber

foaming of wood-fiber/ plastic composites (WPC) with a fine-celled structure can is the most commercially viable plastic processing option and hence is the cell structure of WPC foams, by causing cell coalescence and cell collapse(10).

Sandwich-structured composite - Wikipedia

A sandwich-structured composite is a special class of composite materials that is fabricated by attaching two thin but stiff skins to a lightweight but thick core. The core material is normally low strength material, but its higher thickness provides the sandwich composite with high bending stiffness with overall low density. Open- and closed-cell-structured foams like polyethersulfone polyvinylchloride, polyurethane, polyethylene or Metal composite material (MCM) is a type of sandwich formed from two thin skins of metal bonded to a plastic core in
