mechanical properties: wood lumber versus plastic lumber and

a life cycle assessment (lca) of alkaline copper quaternary (acq) treated lumber in comparison to wood plastic composite (wpc) decking shows that the latter has a significantly higher environmental impact than the former (). thus, the aim of this study was to compare the density, the modulus of elasticity (flexural modulus), and the static flexural, compressive, tensile and shear strengths of wood from coniferae and dicotyledon species from the northern and southern hemispheres 【Get Price】

palm leave and plastic waste wood composite for out door structures

the objective of this paper is to produce an environmentally friendly artificial wood for structural application, by recycling mixed plastic waste and date palm leaves waste. several pretreated wood plastic composites mixtures, using a 1:1 ratio of palm leaves and plastic waste, were designed and developed—namely, polycarbonate (pc mix), polystyrene (ps mix), and polyvinyl chloride (pvc mix). the batch mixture of each type was extruded at different temperature profiles. the density 【Get Price】

wood plastic composites—performance and springer

mance, a homeowner may choose to use wpc decking instead of pressure treated timber because of the ease of plastic product. wood used in wpcs often comes from side streams such as sawdust produced while manufacturing lumber or recovered wood products, and is much cheaper to produce than the plastic that it replaces in many products. this often helps to reduce prices for . but with a lower specific gravity providing for lighter composites. in its own right, wood is a 【Get Price】
