Joining methods for Fiber Reinforced Polymer (FRP) composites − A critical review

Abstract

Fiber-Reinforced Polymer Composites (FRPCs) are widely used materials for various structural applications, particularly for aerospace and automobile industries. The FRPC is a type of composite materials, which combines fibers with polymer matrix and offer exceptional strength-to-weight, enhanced durability, and so on. Irrespective of various advantages, the FRPCs still possess key challenges in joining processes. Effective joining methods are essential for intricate structures, multi-material integration, and sustainability usage of FRPCs. As industries are moving towards sustainable practices, optimizing the joining process for FRPCs without compromising performance and environmental goals becomes crucial. With this focus, a detailed comprehensive review on various joining methods for FRPCs has been made and also highlighted the recent advancement, particularly on adhesive bonding, mechanical fastener and hybrid joining methods. The optimization of joining processes is crucial for cost-effectiveness, production efficiency, and longevity of FRPC structures. The comprehensive analysis and emphasis on the diverse aspects of FRPCs distinguish this review article from existing references, ensuring its unique contribution towards in-depth understanding of joining methods. The review article concludes by underlining the significance and challenges of each joining method for FRPCs and also serves as an effective source of literature in the field of joining methods of FRPCs.
