Comparative study of the morphology, water diffusion, thermal, mechanical, and electrical properties of bamboo fiber/PP/MAPP and areca fiber/PP/MAPP composites

The article presents a thorough comparative study of bamboo fiber/PP/MAPP and areca fiber/PP/MAPP composites, focusing on their morphology, water diffusion, thermal, mechanical, and electrical properties. High moisture absorption, a significant drawback of wood polymer composites, is addressed through the use of compatibilizers and various treatments to enhance water intake and overall performance. The study reveals that bamboo fiber composites exhibit lower moisture absorption and diffusion coefficients due to higher lignin content, making them ideal for outdoor applications. Mechanically, bamboo composites demonstrate superior tensile strength, flexural strength, and impact resistance, attributed to the use of powdered fibers and improved interfacial bonding. Thermal analysis indicates that bamboo composites degrade more slowly, confirming their suitability for high-temperature applications. Conversely, areca fiber composites show better insulating properties, suggesting their potential in electrical applications. The article also explores the use of machine learning models to predict composite performance, addressing challenges in the adoption of natural fiber composites in industrial applications. This comprehensive analysis provides valuable insights into the selection and optimization of natural fiber composites for specific engineering and industrial uses.
