“…It's noteworthy that the strain values decrease with increasing the wood powder content. This is explained by the decrease of plasticity of the obtained composites when the wood fillers are augmented, in good agreement with literature data [24]. The strain behavior of the obtained composites suggest that while incorporating wood powder within the plastic matrix, discontinuity structures occurred which is found to be influencing the mechanical behavior of the material as depicted in the Figure 1, we observe that the lower wood content implies higher strain of the fabricated composite this is in good concordance with several performed stress-strain studies [25].…”

In this paper, we have investigated the stability, mechanical properties, and the microstructure of wood-plastic composites, which were fabricated using recycled high-density polyethylene (HDPE) with pine wood flour used as fillers. Composite panels were obtained using hot-press molding. The tensile and flexural properties of the composites based on recycled HDPE revealed the strength properties of the composites can be improved by increasing the polymer content, also the composite formulation significantly improved the morphology and the stability. Scanning Electron Microscope (SEM) was used to characterize the morphology of the wood particulate/HDPE interface. It was clearly proved from the results that wood-plastic composite (WPC) based on recycled high density polyethylene (HDPE) can be successfully utilized to fabricate stable and strong WPCs.

The water-resistance properties of wood-fiber-reinforced recycled plastic composites (WRPCs) prepared from postconsumer high-density polyethylene (HDPE) and wood fibers from saw mills were studied. Three methods consisting of an alkaline method (AM), a silane method (SM), and a combination of the alkaline and silane methods (ASM) were used to modify the wood fibers. The effects of fiber/matrix mix ratio and surface treatment on the moisture content, thickness swelling, and flexural strength change of the WRPCs, before and after immersion in 608C water for 8 weeks, were studied and analyzed. The flexural fractured surfaces of the WRPCs before and after immersion in hot water were examined, and the fracture mechanism of the WRPCs was discussed. The results showed that the different surface treatments of the wood fibers had significant effects on the moisture content, thickness swelling, and flexural strength of the WRPCs after a long immersion time in hot water. For WRPCs treated by ASM, the moisture content was the lowest, the thickness swelling was at a minimum, and the flexural strength was the highest. Higher water absorption of composites with fiber treated by the AM or SM methods, as compared to those treated by ASM, could be attributed to the incomplete adhesion and wettability between the wood fibers and the polymer matrix, which may have caused more gaps and flaws at the interface.

“…Thus, it is universally used by itself or in combiniation with other vinyl monomers to prepare WPCs (Bakraji et al, 2001(Bakraji et al, , 2002(Bakraji et al, , 2003. The resultant physical and mechanical properties of acrylamide treated wood were significantly improved for the higher polymer loading in the presence of acrylamide (Bakraji & Salman, 2003).…”

“…Concurrently, Mg 2+ interacts with two carboxylate ions as a crosslinking agent and yields ionomer systems (Lu et al 2000). Lithium nitrate (LiNO 3 ), copper sulfate (CuSO 4 ) and sulfuric acid (H 2 SO 4 ) are found to be useful for improving the polymer loading and partly enhanceing the mechanical properties (Bakraji et al 2002;Bakraji & Salman, 2003;.…”
