The study by Jansinak et al. (2025) demonstrates that surface modification of natural fibers, such as pineapple leaf fibers, using silane coupling agents significantly enhances their interfacial adhesion with natural rubber matrices. This improved adhesion leads to a notable increase in tensile strength and better viscoelastic behavior of the resulting composite materials, suggesting that surface treatments are crucial for optimizing the performance of natural fiber-reinforced composites in engineering applications.
