Effect of TiO₂ in Jute/Kenaf/Glass Composite for Interlaminar Shear Strength Using RSM

With their remarkable strength-to-weight ratio and adaptable design features, polymeric composites are widely used in fields like aerospace, automotive, and marine engineering. However, the layered structure of these materials makes them prone to interlaminar shear stresses (ILSS), which can lead to premature failure. ILSS is a critical factor in assessing the structural integrity and effectiveness of polymeric composites, particularly in applications where delamination and shear-induced failures are concerns. This study investigates key variables influencing ILSS in polymeric composites, including the effects of nanoparticle reinforcement, fiber orientation, and fiber sequence. Additionally, it explores the impact of hand lay-up techniques. Employing response surface methodology and short-beam shear tests, along with other experimental and analytical methods, this work quantifies ILSS. Results indicate that incorporating nanofillers, optimizing fiber lay-up techniques, and carefully selecting fiber orientations can significantly enhance ILSS.
