Hybrid composite laminates are formed by combining two or more types of reinforcement fibers within a polymer matrix to achieve improved strength-to-weight ratio, stiffness, impact resistance, and cost effectiveness. In modern aerospace and automotive structures, hybrid composites are increasingly used due to their superior mechanical performance and among the major design parameters, fiber orientation and stacking sequence significantly influence the structural behavior and failure characteristics of hybrid composite laminates. Fiber orientation determines the directional strength and stiffness, whereas stacking sequence controls stress distribution through laminate thickness, bending stiffness, interlaminar shear stresses, delamination resistance, and fatigue life. This survey paper reviews experimental and numerical research works on hybrid composites such as carbon/glass, basalt/carbon, Kevlar/glass, and natural fiber/synthetic fiber hybrids. The effect of ply orientation (0°, ±45°, 90°) and stacking sequences such as symmetric, asymmetric, cross-ply, angle-ply, and quasi- isotropic configurations is critically analyzed. The literature reveals that 0° plies provide maximum tensile strength, ±45° plies improve shear performance and impact energy absorption, while 90° plies contribute to transverse stiffness. Stacking sequence is found to play a dominant role in flexural and impact properties, where placing high modulus fibers on outer layers improves bending strength, whereas tough fibers on outer layers enhance damage tolerance. Research gaps, challenges, and future scope are also discussed.
