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 hemp fibers were mixed with 90% High Density Polyethylene (HDPE) and fabricated with injection molding machine after gone through mercerization process of 5% NaOH in 24 hours. For wood dust fiber, Kumar et al [26] managed to get the maximum of 28.29 MPa and 1335.20 MPa of tensile and flexural strength which through 15 % of Epoxy and Hardener using glass vacuum chamber as its fabrication method. But then, Kumar did not mention any mercerization process in the making of his composite material testing.…”

Abstract. Natural fibers, characterized by sustainability, have gained a considerable attention in recent years, due to their advantages of environmental acceptability and commercial viability. In this paper, the characterization of natural fibers including the mechanical properties and alkalization of fibers is presented. Most recent study had gone through the mercerization process to improve the toughness of natural fibers; which is a well-known hydrophilic material. Traditional reinforcement method was commonly used to fabricate a natural fiber composite such as hand lay-up and mold press due to its convenience in terms of time and cost. Also, different kind of matrix material used in different kind of natural fibers gave high impact on the tensile and flexural test result. By selecting appropriate chemical treatment, matrix material and fabrication method, the tensile and flexural test gives different results and findings. As most researchers tend to use metals to create corrugated cores for sandwich structure, it is possible to develop this structure using natural fibers such as kenaf, wood dust, and other natural fibers.

“…The factors, filler content, sliding velocity, and normal load, in that order, were the most significant factors that affected the specific wear rate (Kranthi and Satapathy 2010). Wood composites processed and filled with seven types of epoxy adhesives were also studied by Kumar et al (2014). It was found that the mechanical properties increased up to a certain filler loading, and then they gradually decreased (Kumar et al 2014).…”

The design of an epoxy adhesive was investigated by a 2 K design of experiment (DOE). All the assigned parameters showed no significant effect for both curing and mechanical properties, except for bisphenol A (BPA), which showed a significantly negative effect on the heat distortion temperature (HDT) of the cured samples. Adding dicyandiamine (DICY) into the hardener retarded cure time and also caused an incomplete curing at room temperature. Curing at 110 °C and 150 °C post curing were the optimal conditions and 20 g of DICY with 50 g of triethylenetetramine (TETA) was optimized. Adduct obtained from aliphatic epoxy (RD108, 14.63 g) and TETA (7.71 g) were selected and employed as hardener ingredients. The incomplete crosslinking reaction was the main reason for the inferior properties at high RD108 loadings. The toughening by blending with polycarbonate (PC) was explored, and 5 phr of PC was selected. Limitation of resin/fiber infusion due to high viscosity was observed. Dilution of the solvents using ethyl acetate (EA) and methyl ethyl ketone (MEK) to reduce viscosity was explored. The mechanical properties of the wood samples manufactured from the EAdiluted epoxy were superior to the MEK dilution. The lower boiling point and good solubility of EA were explained.
