“…Generally, materials with the values of contact angle more than 90° are considered to be hydrophobic, while less than 90° are hydrophilic 59 . As Figure 5 shown, the contact angle of WPCs were above 90° and therefore can be classified as hydrophobic materials likely duo to their smooth surface and high level of polypropylene content 60 . Lower contact angle has been observed for both C. versicolor and P. placenta decayed specimens, which implied that fungal decay increased the surface wetting ability of WPCs.…”

“…This finding is consistent with that of Butnaru et al 59 and can be probably attributed to the more rough and cracked surfaces of WPCs caused by the biodegradation of fungi, which has been clearly indicated by the results of SEM in Figure 1. Therefore, the surface of decayed samples consequently exhibited significant modification to attract water molecules and higher water uptake 60 …”

This study investigated the associations between wood species and fungal resistance, as well as the effects of fungal decay on the properties of mechanical, chemical, and water absorption of wood polypropylene composites (WPCs) filled with white poplar, moso-bamboo, Chinese fir, Ramin, white pine, and rubber wood. Experimental results on weight losses and surface morphology both showed that fungal resistance of WPCs varied significantly with wood fiber species. Chinese fir and rubber wood filled composites separately presented the most and least durability against Coriolus versicolor (white rot) and Poria placenta (brown rot). In addition, fungal decay produced great differences in the properties of mechanical, chemical, and water absorptions between non-decayed and decayed composites. The decayed composites showed lower MOR, tensile strength, and impact strength, as well as higher MOE and water absorptions compared with non-decayed samples. These findings suggest that fungal decay could bring out dramatic influences on various properties of WPCs.

“…The results of FTIR analysis of rHDPE and its RLFs filled biocomposites are shown in Figure 3. The peaks are assigned in Table 1 by referring on different works 6,28–31 . Figure 3(a) shows the IR spectrum of RLFs and the clear peak at 3306 cm −1 , associated with the presence of OH group, could be due to the presence of the cellulose in the vegetable fiber.…”

Recycled plastic (rHDPE) was coupled with different weight percentage of ronier palm leaf fiber (RLFs) to prepare eco‐friendly polymer biocomposites. Fourier transform infrared analysis, tensile test, dynamic rheological test, hardness test, scanning electron microscopy (SEM) analysis, and density measurement were used to determine the structural, mechanical, morphological and physical properties of the biocomposites. The modulus showed excellent improvement with the addition of RLFs. G′ and G″ were found to increase with the increment of both the filler content and the angular frequency. At low frequencies, the loss factor was increased with the frequency and decreased with the RLFs content. However, at high frequencies, it was decreased with both the angular frequency and the RLFs content. The complex viscosity η* was found to be increasing and decreasing with the RLFs content and the angular frequency, respectively. SEM micrographs of tensile fractured surfaces of biocomposites show pulled out RLFs zones and voids due to the presence of agglomeration. Finally, the experimental Young's modulus data was compared with theoretical predictions. A good fit was obtained with Einstein Model.

“…As a result, converting plastic trash into value-added products has emerged as a viable option for boosting the world economy from plastic waste [3,5]. Wood, as a natural renewable material of biological origin, has numerous advantages in a variety of applications, ranging from structural and construction materials to furniture and transportation to raw materials for energy production, due to its unique microscopic structure, abundance, relative ease of work, and good visual effect [6]. Only a few of the advantages of wood-sawdust over other typical wood composite materials include better insulating qualities, resistance to water absorption, fire performance, and strength properties.…”

 Effects of alkyls treatment of Sawdust on the mechanical and physical properties of wood-plastic composites are investigated.  Effects of depolymerized polyethylene terephthalate (DPET) and VV/55 on the properties of composite.  50% of the produced blends in wood-plastic composites are used for waste recycling and environmental protection.Plastic waste has become one of the humanities and the ecosystem balance serious environmental Challenges. Furthermore, it is the primary source of plastic pollution because it is inexpensive, widely available, and frequently discarded. Using various waste materials and side fractions as part of woodplastic composites is one way to promote the circular economy (WPC). Several environmental benefits can be realized by using recycled plastic, including extending the usable life of plastic, reducing waste, contributing to the development of trash recycling, and preventing resource depletion. One of the most efficient recycling processes is glycolysis; the (PET) is depolymerized by ethylene glycol in continuous stirring reactors at temperatures between 200 and 220•C using glycol as solvent. This work concentrates on the experimental investigation of composite materials from DE polymerization PET, Unsaturated polyester, and VV/55 as a matrix and wood sawdust as reinforcement. The composite samples were checked by the Hardness test, water test, and density test. According to the experimental results, the optimum value is at (2%) wood percentage, giving high hardness value, low density, and low water absorption.
