<p>High-performance textile reinforced composites are widely used in military, defense, aerospace, marine, automobile, and sports industries. These composites offer good in-plane properties but are prone to delaminate in the thickness direction. Thus, the interlaminar fracture or delamination needs to be characterized due to major design concerns. Under the influence of external loading, micro-level cracks can initiate or propagate in the structure and are capable of deforming it. This research intends to investigate the Mode-II interlaminar fracture toughness of plain and twill woven carbon, Kevlar monolithic, and their interyarn hybrid textile composite laminates by placing both yarns separately in the length direction. Eight different laminate configurations are fabricated using the vacuum assisted resin transfer molding (VARTM) technique. Mode-II interlaminar fracture toughness characterization is performed on the Instron 8862 system in non-precrack (NPC) and precrack (PC) configurations using an end notched flexure (ENF) specimen. The fracture toughness is calculated using the compliance calibration (CC) data reduction method. Results reveal that plain woven composites show higher fracture toughness than twill woven composites, PC fracture toughness is higher than NPC fracture toughness, and in the hybrid laminate configurations, plain woven carbon–Kevlar hybrid composite laminate shows the highest fracture toughness when carbon yarn is placed in the length direction.</p> Graphical Abstract <p></p>
