This study focuses on determining the most effective reinforcement architecture for textile composite materials. There exist in-plane properties for plain-woven reinforcements, but lack on strength in the out-of-plane range. This has led to the popularization of advanced reinforcement structures, like 3D knitting preforms, 3D needle-punched fibers, 5D braiding preforms, and 3D weaving. The architecture of reinforcement used in fiber-reinforced polymer composites (FRPCs) influences the mechanical property of the composite. Several studies have already investigated the reinforcement structures, but they fail to address the comparative analysis of several reinforcement structures and their trade-offs in mechanical behaviour between conventional 2D reinforcements and advanced 3D structures. This work reviews the effect of different reinforcement architectures-plain-woven fabrics, 3D knitted preforms, 3D needle-punched fibers, 5D braided preforms, and 3D woven fabrics-on the mechanical performance to fill all these voids. By listing disadvantages and advantages of every architecture, this work throws light onto the optics of reinforcement selection for accomplishing better composite properties and economical design without compromising performance.
