Mechanical properties of fabricated hybrid composites infused with Heat-Treated alkali sisal fiber and SiC particles: a quantitative analysis

Hybrid composites made up of epoxy-based matrix materials and infused with reinforcement and a filler material continue to evince keen interest among researchers and technologist. Hybrid composites made up of epoxy based matrix materials and infused with reinforcements and a filler material continue to evince keen interest not only amongst researchers and technologists as well since they are found to possess superior technological characteristics, a requirement for critical engineering applications. The present work describes the fabrication of hybrid composites made up of epoxy as a matrix material infused with 18% NaOH-treated and heat-treated sisal fiber. In addition, SiC particles are used as a filler material and subsequent evaluation of typical mechanical properties. The results of this investigation revealed that epoxy-based matrix material infused with alkali–heat-treated sisal fibers as a reinforcement and SiC particles a filler material exhibits superior tensile, flexural, shear and compressive characteristics in comparison with other test sample experimented in this work. This is attributable to the ability of alkali treatment enabling the removal of organic material from the sisal fiber which helps the matrix material to fill these voids. SiC particle is formed to fill the force on the fibers thus making it stronger and hence capable of withstanding higher magnitudes of tensile, flexural, shear and compressive loads. Micrographic analyses further confirm the experimental research.
