- Abstract
The escalating use of fiber-reinforced composites (FRCs) in aerospace, defense, automotive, and renewable energy industries underscores the need for a comprehensive understanding of their impact resistance and damage tolerance. This review meticulously examines low-velocity impact (LVI) on FRCs, covering impact mechanics, velocity classification, energy absorption, fiber architecture, and hybridization. Emphasizing the critical importance of damage assessment, the study analyzes intricate failure mechanisms and damages induced by LVI, addressing their potential impact on composite structural attributes. The paper critically reviews parameters influencing impact resistance and damage mechanics, evaluating performance through instrumented drop-weight impact testing. Additionally, the review explores nondestructive testing methods crucial for ensuring the reliability of composite structures. The aerospace sector and other applications requiring enhanced dynamic loading characteristics stand to benefit from a deeper understanding of composite behavior under transient impact loading. Specifically focusing on woven textile-reinforced composites, which offer specific material properties and a cost-effective manufacturing route. However, their susceptibility to out-of-plane impact loading leads to various failures, including delamination and spalling, limiting their applicability in advanced scenarios where structural integrity is paramount. It discusses advanced technology like 3D weaving as reliable methods to enhance impact resistance, damage tolerance, and delamination resistance. Notably, 3D woven composites demonstrate superior through-thickness fracture toughness, eliminating delamination as a failure mode. The findings offer valuable insights for designing structures with enhanced compression after impact and through-thickness tension characteristics. Overall, this review consolidates key advancements, challenges, and future prospects in the realm of woven composite materials and their behavior under impact loading, providing a valuable resource for academics and industry professionals alike.
