The ongoing research focuses on exploring the potential of Careya arborea (CA) fiber, banana fiber (BF), and epoxy composites as sustainable alternatives to petroleum-based products synthetic fibers. aim is enhance interfacial bonding overall performance these while reducing reliance traditional materials. study investigates adhesion between CA BF (both chemically treated), with polylactic acid (PLA) coating. Specifically, it examined how PLA coating affects mechanical properties, including tensile strength, flexural impact resistance, water absorption behavior, fabricated composites. Mechanical characterizations composite specimens are conducted following ASTM standards. PLA-coated NaOH-treated significantly improved their strength (20.56%) (16.7%), reduced capacity (by 47.6%) compared untreated ones. These findings highlight promise using treated natural fibers coatings create more high-performance

The addition of low-loading content nanofillers may improve the material properties polymer-based nanocomposites. This improvement directly corresponds to density well-dispersed in matrix. However, for higher nanofiller loadings, nanocomposites' not only be improved but also degraded due agglomeration. complex phenomenon, where tend form agglomerates with enhancement volume fraction, poses significant challenges materials science and nanotechnology. It has been proven that agglomerations hinder performance nanocomposites thwart unique most aspects. Graphene, one used nanofillers, plays a remarkable role Therefore, key focus current review is provide insight into impact agglomeration on various such as tensile, flexural, fracture, fatigue, thermal, electrical, barrier characteristics polymer reinforced by graphene-based structures. A comprehensive factors leading graphene was presented. concluded could developing nanocomposites, controlling were discussed depth, highlighting issue's complexity.
