Systematic Review : Wood-plastic Composites as Sustainable Solutions for Composite Structures
Year: 2025
Type: review
Study design: Systematic Review
Abstract: This paper reviews recent advances in wood-plastic composites (WPC) research to explore their potential in composite structures. Utilizing the Systematic Search Flow methodology, the composition, production strategies, and physical-mechanical performance of WPC were analyzed. The extrusion process, whether isolated or combined with other methods, stands out for thermoplastic-based WPC, allowing continuous production and high processing rates. Polypropylene is commonly used as a matrix, combined with residual fibrous fillers that enhance stiffness and strength but also increase water absorption. The use of compatibilizing agents can mitigate this absorption and improve mechanical performance. The manual hand layup method is prevalent for thermoset composites, offering longer handling times and resulting in dimensional stability and thermal resistance; however, it heavily relies on the operator's skill, limiting process consistency. The versatility of WPC positions them as a promising solution for construction, addressing plastic waste pollution and deforestation. Nonetheless, further research is needed to enhance durability and performance while exploring new materials and techniques. This study comprehensively covers these aspects, employing graphical tools to illustrate the complexities involved and providing in-depth analyses of how these factors influence the physical-mechanical behavior of WPC.
