“…During this stage, the DCP generates free radicals abstracting hydrogen atoms from the HDPE molecules to create a crosslinked structure. 22 Following this critical analysis, a comprehensive scheme (mixing technique and processing conditions) is presented in Figure 2 to select the production steps for xHDPE with wood fibers. The amount of DCP was held constant at 1 phr, 1 while different fiber contents (treated or untreated) between 0 and 50 wt%.…”

This paper presents a comprehensive investigation into the manufacturing of high‐performance wood‐crosslinked high‐density polyethylene composites (WxHDPEC). In particular, the effect of maleated polyethylene (MAPE) treatment and concentration (0–50 wt%) of maple wood fibers is investigated. The samples were produced via dry‐blending followed by compression molding and a set of characterization was performed including chemical, morphological, mechanical, thermal, and physical properties. The gel content was found to increase with increasing wood fiber content, while the surface modification significantly improved the tensile strength (11%), tensile modulus (298%), flexural strength (138%), and flexural modulus (81%). Thermal analyses also showed improved thermal stability and higher thermal resistance for the treated composites. Finally, the Shore D hardness increased by 11.0 (from 61.5 to 72.5) and 12.1 (from 61.5 to 73.6) points, while the Shore A hardness increased by 7.5 (from 91.5 to 99.0) and 8.1 (from 91.5 to 99.6) points for the untreated and treated composites, respectively. These improvements are attributed to effective adhesion between MAPE‐treated wood fibers and the xHDPE matrix. The findings not only advance our understanding of these complex materials but also provide alternatives for various applications from construction to automotive engineering.Highlights High‐performance wood‐reinforced crosslinked high‐density polyethylene was produced. The effect of maleated polyethylene (MAPE) treatment and maple wood fibers was studied. Higher crosslink density in MAPE‐treated wood‐xHDPE was obtained. Wood‐crosslinked high‐density polyethylene composites have better properties.

In this study, high density polyethylene (HDPE) was combined with dicumyl peroxide (DCP) to produce crosslinked parts via rotational molding. The effect of DCP content (0.1–2.5 phr) on the crosslinking degree was investigated to determine its effect on the chemical, mechanical, physical, and thermal properties of HDPE. The gel content and crosslink density was found to increase with DCP content. These trends led to a reduction in the degree of crystallinity, melting, and crystallization temperature. Thermogravimetric analysis (TGA) showed that crosslinked HDPE (xHDPE) has higher thermal stability than the neat matrix in both air and nitrogen atmosphere. In addition, a direct relationship was observed between improved thermal resistance and higher impact strength. Finally, relationships between the tensile properties of xHDPE and the degree of crystallinity were observed, which were all controlled by the level of crosslinking. These results have the potential to advance the manufacturing of high performance materials suitable for a wide range of applications such as automotive parts, agricultural products, chemical storage tanks, large waste containers, and fuel tanks in general.
