Mechanical Property Assessment of Hybrid Fiber Reinforced Composites Through Experimental Research

Natural fibre reinforced composites are gradually taking the place of synthetic fibre composites due to its inexpensive cost, low density, and ease of supply. Furthermore, the addition of some waste materials to composites has remarkable properties that are attracting interest from a wide range of technical domains. Fibre reinforced with glass, carbon, and jute were used to generate hybrid composites. As a filler, different amounts of eggshell powder were mixed with the polymer matrix material. Evaluating the tensile and compressive strengths of hybrid composites at room temperature is crucial to understanding their mechanical characteristics. Tensile strength is the highest stress a material can withstand before breaking when stretched or pulled, and compressive strength is the highest tension a material can withstand when squeezed or compressed before failing. The test findings showed that the characteristics were significantly improved by adding 2% eggshell powder. Glass-based composites gain 35% more compressive strength and 19% more tensile strength when 2% eggshell powder is added. Carbon-based hybrid composites have a 3% increase in tensile strength and a 16% increase in compressive strength. Jute-based composites showed increases of 27% in compressive strength and 4.5% in tensile strength. Eggshell-powered being characteristics such as increase matrix density, enhanced interface bonding, and strain energy absorption therefore significantly increasing tensile and compressive strength with adding into glass fiber. Glass fiber is to be considered as a brittle material. By adding the eggshell powder in carbon and jute-based composite, the tensile and compressive strength may be increased but not more when compared to the glass fiber composite because the response of characters of eggshell powder is better performance in glass fiber composite.
