Improving the Mechanical and Interfacial Properties of Bhendi Fiber via Chemical Surface Treatments
Abstract: Because of its primary benefits—moderate strength and stiffness, low cost, and being a renewable, degradable, and ecologically friendly material—natural fibers are believed to have potential use as reinforcing agents in polymer composite materials. Due to their inherent hydrophilicity, they have a tendency to retain moisture, which can impair or soften the fibers' adhesion to the surrounding matrix. This can have an impact on the performance of composite materials used in …
