<p>Through its impressive strength-to-weight ratio and versatile design capabilities, polymeric composites have become a staple in sectors such as aerospace, automotive, and sustainable applications. Nevertheless, the layered structure of the material makes it liable to interlaminar shear stresses, which can result in early failure. When assessing the efficiency of polymeric composite, ILSS is an important factor, especially in situations where delamination and shear-related failures are a concern. This work investigates the variables affecting ILSS in polymeric composite materials and assesses various approaches to improve this characteristic. This study examines how reinforcement Nano-particle, fiber orientation, and sequence affect ILSS. Furthermore, the effects of hand lay-up techniques are looked into. The work uses Response surface methodology and short-beam shear experiments, among other experimental and mathematical methods, to quantify ILSS. The findings suggest that including nanofillers, refining fiber lay-up techniques, and utilizing fiber orientation will considerably improve ILSS for sustainable development materials.</p>
