This study investigates the influence of stirring speeds variation (50 rpm, 100 rpm, and 150 rpm) on tensile strength of fiberglass composite fabricated by Vacuum Assisted Resin Infusion (VARI) method. The VARI process involves injecting resin into dry fibers placed inside a plastic bag under low pressure, ensuring complete wetting of the fibers. The research aims to identify the optimal stirring speed for composite production by performing tensile tests. Results show that the stirring speed of 150 rpm yields the highest tensile strength, while the 50 rpm variation exhibits the lowest. Photomicrographs reveal the presence of voids in certain area , impacting composite density. The study concludes that stirring speed significantly affects tensile strength and density.
