Study on Water Absorption Characteristics, Various Chemical Treatments, and Applications of Biological Fiber-Reinforced Polymer Matrix Composites

Abstract

This study presents an extensive survey of the many surface treatments that may be given to natural fibers for use in advanced composites. When put into reality, the primary disadvantages of working through biological fibers are the increased level of moisture intake that natural fibers possess as well as their low dimensional stability. The fundamental purpose of applying surface treatments to natural fibers is to optimize the bonding strength as well as the pressure transferability in composites made of biological natural fibers. Natural fiber-strengthened polymer composites (NFPC) have overall mechanical qualities that are strongly dependent on the morphological, aspect ratio, hydrophilic propensity, and high stiffness of the natural fibers that are employed in the composite. Cellulosic fibers are being studied for their effects both before and after being used as reinforcements for thermoset and thermoplastic polymers. Some of the chemicals utilized in treatments include alkalis, silane, acetyl, benzoylation, acrylation and polyamide grafting, maleated linking agents, ammonium nitrate, peroxide, phenoxy, stearic acid, potassium chalcopyrite, triazine, synthetic derivatives of fatty acids (oleoyl chloride), and fungi. After chemical treatment, composites made from organic fibers are stronger and more dimensionally stable than the untreated sample.
