Abstract
Currently, there is a steady increase in the production of plastic products using rotational molding. According to Market.US, a reputable marketing company, the average annual growth rate of rotational molding in the world from 2025 to 2034 is expected to be 5.7%. To further promote the "green economy" principles in rotational molding, there is a need for a significant increase in the use of renewable raw materials, particularly wood-based products. This review provides a comprehensive overview of research into the development of polyethylene-based formulations reinforced with lignocellulosic fibers such as sisal, pine, flax, and maple for rotational molding. Research on fiber-reinforced composites shows that both the type and content of lignocellulosic fibers significantly affect the final properties of the resulting products. For example, impact strength and hardness depend significantly on fiber inclusion, with optimal results achieved at a certain fiber concentration. Chemical treatments such as mercerization or other surface modifications are often used to improve fiber adhesion to the matrix, thereby improving mechanical properties. Overall, understanding the relationship between processing conditions, fiber characteristics, and chemical treatment is critical for tailoring composite properties to various industrial applications.
