Abstract
Natural fiber composites have gained much interest for application in industries, such as shipbuilding (for small boats), automotive manufacturing, and aerospace. Researchers have been investigating the use of natural fibers, such as alfa, jute, and sisal, as reinforcement in composite materials, due to their desirable physicochemical and mechanical properties. However, the hydrophilic nature of vegetable fibers presents a challenge, because it results in poor adhesion between the fibers and the polymer matrix in composites. This study focuses on the effects of alkaline treatment on the morphological structure of Cynodon dactylon plant root fiber. The treatment lasted 1 hour and used sodium hydroxide solutions at concentrations of 2%, 4%, 6%, and 8%. The fibers were characterized by XRD, FTIR, TGA, EDX and SEM analyses.
