“…The density values of the WPCs prominently increased with the addition of wood flours. It is believed that a higher density of lignocellulosic Iroko wood flour, which has a high cell wall density, might be responsible for the increased density of the WPCs (Mengeloglu and Karakus 2008;Mengeloğlu et al 2015).It is reported that the usage of lignocellulosic materials as a filler increases the density of PP-based (Steckel et al 2007;Özdemir et al 2013;Mengeloğlu et al 2015;Mazzanti et al 2016;Basalp et al 2020;Mengeloğlu and Çavuş 2021) and HDPE-based (Ramezani Kakroodi et al 2013;Başboğa et al 2020) composites. PP-based WF and TiO2-filled composites were produced in the density range of 0.893 to 1.076 g/cm 3 .…”

This study investigated the effects of Iroko wood flour (WF) and nano-titanium dioxide (TiO2) concentration on the properties of polypropylene (PP)-based composites, including accelerated weathering resistance, tribological behavior, thermal stability, physical characteristics, mechanical strength, morphological features, color changes, and surface roughness. The results showed that the presence of WF and TiO2 significantly influenced the density, hardness, thermal stability, crystallinity, coefficient of friction, and wear rate of the composites. Both fillers positively impacted the tensile strength, flexural strength, and flexural modulus of the composites, although the elongation at break values decreased. TiO2 addition enhanced thermal stability and protection against UV radiation, whereas using wood flour negatively affected color properties. Moreover, the surface roughness of the composites was affected by weathering time and wood flour content. These findings highlight the potential of WF and TiO2 as effective fillers for enhancing PP-based composites’ properties and weathering resistance.

“…Therefore, compared with inorganic fillers (e.g., mineral fillers and glass fibers) used in reinforced composites, WPCs show many advantages such as reducing the proportion and cost of the plastic matrix, increasing the stiffness of the plastic matrix, improving the physico-mechanical properties and processability of wood materials, renewability, low maintenance requirements, and environmentally friendliness [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. In addition to wood particles or fibers, various agricultural wastes, such as bagasse [ 20 , 21 ], bamboo [ 16 , 18 ], cotton [ 11 ], coconut [ 22 ], hemp fiber [ 12 ], kenaf fiber [ 23 ], pineapple leaf [ 11 ], palm [ 9 , 24 ], rice husk [ 25 ], red pepper fruit stem [ 26 ], and straw [ 27 ], were also used as reinforcements or fillers for the thermoplastic composites. However, little information is available regarding the recycling and reuse of the pomelo waste.…”

The purpose of this study is to compare the characteristics of wood–plastic composites (WPCs) made of polypropylene (PP) and wood fibers (WFs) from discarded stems, branches, and roots of pomelo trees. The results show that the WPCs made of 30–60 mesh WFs from stems have better physical, flexural, and tensile properties than other WPCs. However, the flexural strengths of all WPCs are not only comparable to those of commercial wood–PP composites but also meet the strength requirements of the Chinese National Standard for exterior WPCs. In addition, the color change of WPCs that contained branch WFs was lower than that of WPCs that contained stem or root WFs during the initial stage of the accelerated weathering test, but the surface color parameters of all WPCs were very similar after 500 h of xenon arc accelerated weathering. Scanning electron microscope (SEM) micrographs showed many cracks on the surfaces of WPCs after accelerated weathering for 500 h, but their flexural modulus of rupture (MOR) and modulus of elasticity (MOE) values did not differ significantly during weathering. Thus, all the discarded parts of pomelo trees can be used to manufacture WPCs, and there were no significant differences in their weathering properties during 500 h of xenon arc accelerated weathering.
