The present study examines the impact of TiO2 nanoparticles on the fatigue behaviour of composite materials with internal or exterior cracks. In order to guarantee that the TiO2 nanoparticles are completely dispersed throughout the base material, the nanocomposite material is created by combining them with epoxy using an ultrasonic mixer, varying weight percentages of particles as 1%, 2%, and 3%. The epoxy is supplemented with TiO2 nanoparticles. A single layer of woven roving glass fibre is added to the synthesized epoxy nanoparticles to create various hybrid nanocomposite materials, which have a consistent weight of 10%. After that, lamellar hybrid composite nanomaterials are made by hand with a vacuum device. Experimental specimens for tensile and fatigue tests are produced in compliance with ASTM guidelines. According to the data, the hybrid nanocomposite with the highest fatigue-stress limit is with 3% of particles. Additionally, it is generally noted that the stress behaviour of this material is improved by the inclusion of TiO2 nanoparticles.
