Summary: This study investigates the properties of WPCs made from wood flour and wood pellets, showing that composite products from wood pellets have higher density but lower tensile strength, tensile modulus, and impact strength compared to those made from wood flour. Flexural properties of composites made with pellets were higher without MAPP, but lower with it. Overall, the mechanical property differences between the two were low (0.5-10%) depending on the specific WPC formulations. Statistical analysis indicated no significant differences in material properties between composites made from wood flour and wood pellets, with some situations showing better WPC properties using wood pellets.

Summary: This paper investigates the preparation of environmentally friendly wood-plastic composites (WPCs) using corn stalk as the raw material. By optimizing the pretreatment method and selectively removing lignin and hemicellulose, the mechanical performance of the WPCs is improved. The sample with both lignin and hemicellulose removed shows the highest crystallinity and fibrous morphology, and exhibits significantly increased tensile strength, modulus, flexural strength, and modulus compared to regular WPCs. Additionally, the extracted lignin and hemicellulose can be further utilized for valuable biochemical products, adding value to both WPC materials and biorefinery products.

Summary: The study evaluated the mechanical and hydrophobic properties of wood plastic composites (WPC) prepared by hot molding with five different recycled plastics and poplar flour. The WPC showed excellent tensile and flexural strength, good hydrophobicity, and a strong, hydrostable structure with minimal formaldehyde emission, making it a potential sustainable alternative to traditional wood-based panels for furniture materials.

Summary: The properties of experimental wood plastic composite (WPC) panels made from rubberwood, waste PET, and silica were evaluated in this study. It was found that increasing PET content reduced water absorption while improving compressive strength and hardness. Higher silica content adversely influenced mechanical properties but enhanced water absorption.

Summary: The study focused on recycling plastic waste by manufacturing wood-plastic composites with improved mechanical properties. Increasing the wood powder ratio resulted in higher bending strength, while reducing the water swelling ratio of the plastic matrix and wood particles led to better mechanical properties. The type of wood species also played a key role in determining the dimensional stability and mechanical properties of the composites.

Summary: The study focused on investigating the mechanical properties of wood-plastic composites (WPC) produced through a two-step extrusion process. It was found that different stress levels had varying effects on the creep behavior of WPC, with higher stress levels leading to brittle fractures more quickly. The Findley model was able to predict creep behavior at different stress levels, while the fractional-order model showed the highest fitting degree for high-stress levels.

Summary: In this study, wood veneer/wood flour-polyvinyl chloride composites (WWPVCs) were treated with a silane coupling agent to improve their interfacial bonding, mechanical properties, and resistance to moisture and heat. The treated samples showed superior performance compared to those treated with other interface modifiers. Silane coupling agents are easily prepared and environmentally friendly.

Summary: Wood has been used as a building material due to its unique properties, but the pollution in the synthesis of wood-based composites is increasing. It is now a mainstream trend to use environmentally friendly materials and adhesive-free bonding technology to prepare wood-based composites. This paper summarizes the types of wood-based composites, pollution problems in the preparation process, and focuses on the green preparation technology and performance advantages of advanced wood-based composites. The adhesive-free hot-pressed technology is the most environmentally friendly method. Furthermore, the paper looks forward to the development of advanced wood-based composites with new functions through green preparation technology.

Summary: Wood-plastic composites (WPCs) have attracted considerable attention in academia due to their desirable mechanical characteristics and long-lasting nature. However, imperfect interface compatibility within the multi-phase architecture of WPCs leads to fungal attacks, degrading their mechanical properties. This article reviews the critical role of interfacial compatibility in determining the overall antimicrobial performance of WPCs, and summarizes commonly used antimicrobial agents and their mechanisms of action.

Summary: Wood plastic composites (WPCs) were prepared by extrusion molding with eucalyptus powder, polyvinyl chloride (PVC), and silica as additives. The mechanical properties, creep behavior, thermal properties, and cross-section microstructure of the composites were analyzed. The results showed that increasing silica content initially increased and then decreased the tensile strength, bending strength, and impact strength of the WPCs. The addition of 3.0% silica led to maximum values for these properties. The strain value of the 3.0% SiO2-eucalyptus/PVC wood plastic composite was significantly higher compared to the other samples at different stress levels. The pyrolysis process of the composites showed a similar trend with different silica content.
