摘要：The utilization of fiber-reinforced composite (FRC) materials gradually increased in industrial applications. The amounts of fiber composites used in modern aircraft surpass half of the vehicle weight [1]. It was also found that the usage of composites grater in the container ships, modern yachts, lightweight boats[2]. Even a greater share of composites has been using in automobile applications, approximately 50% of total vehicle volume [3]. Toyota automobile company first started using polymer composites to reduce the weight and increase the efficiency of the vehicle [4]. Since the metal components are and will be essential in these structures, the issue of linking composite and metal components becomes increasingly more significant as the portion of composite components in the structures increments. The joint utilized in a composite structure is typically the most sensitive part of the structure and consequently decides the primary efficiency [5]. The mechanical fastening (bolted joints) and adhesively bonded joining are the most popular ways of joining the fiber composites [6–7]. Despite joining methods and fabrication errors adhesive and bolted joints are used for both metal elements and fiber composites [8].
