Abstract The use of adhesive joints has increased rapidly in the past decades. Driven by the growing demand for lightweight structures, composite adherends have increased in popularity, benefiting from their high specific mechanical properties and design tailorability. However, composites are typically weak in the transverse direction, which can cause premature failure by delamination. Several techniques, aimed at reducing stress concentrations and increasing the transverse strength of the adherends, are discussed and compared in terms of material arrangement and geometry design. Lastly, a short summary on prominent features of the techniques is given. The paper is intended to provide guidelines for the design of adhesive joints with composite adherends.

ABSTRACTBy using fiber-reinforced plastics as the material for lightweight structures, adhesive bonding becomes an increasingly focused solution for joining these components. In comparison to bolted joints, adhesive bonding has a lot of known benefits, e.g. sealing, no weakening of adherends and a homogeneous load transfer. However, the stress distributions in single-lap joints are not homogeneous all over. Both the shear and peel stress distribution have a peak at the overlap ends of the joint ...

Abstract Scarf or stepped-lap repairs are desirable for composite structures in aerospace, especially where a flush finish is required. Damage tolerance is a critical issue in the repair design. This paper investigates and compares the damage tolerance of scarf and stepped-lap joints (repairs) under quasi-static loading using finite element analysis (FEA). The damage was represented by a flaw embedded in the bondline between composite adherents. 3D FE models were built for both scarf and stepped...

Carbon fiber reinforced polymer matrix composite laminates with standard thickness plies (0.125 mm) usually have weak interlaminar shear strength, meanwhile, for thin-thickness laminate structures such as aircraft wing skin, it is difficult to design a balanced laminate with the standard plies. It is a possible way to improve the interlaminar shear performance of carbon fiber reinforced polymer composite laminates and enlarge the design space of the thin-thickness structures by using thin-plies ...

AbstractThe joints are usually the weakest part of the engineering structures. In this study, the employment of wavy edges for increasing the adhesive joint load-bearing capacity is considered. The effects of geometric parameters of the wavy edges on the strength of the adhesive joints were investigated, experimentally. Two different adhesives, Araldite 2015 and Epoxy RL440/HY441 as ductile and brittle adhesives were used, respectively. The finite element model was also developed for more invest...

Abstract The use of composite structures in the automotive industry aims to produce vehicles able to meet both fuel economy and safety standards. This work focused on the improvement of static and impact strength of composite adhesive joints, avoiding early delamination of the composite. The techniques applied are mixed adhesive combinations (use of two adhesives in one overlap) and the use of crash resistant adhesives. Experimental results demonstrated that a crash resistant adhesive provides t...

ABSTRACTFriction spot joints of aluminum alloy 2024-T3 and carbon-fiber-reinforced polyphenylene sulfide (CF-PPS) were produced with the PPS film interlayer. Mechanical grinding, sandblasting, and sandblasting combined with plasma activation were performed on the composite part to enhance the interface adhesion. The surface features – roughness, wettability, and chemical activation – were correlated with the ultimate lap shear force of the joints. The composite surface with the highest surface r...

Abstract null null null Most studies usually use load-displacement curve or post-failure analysis to understand the mechanical behaviour of hybrid bonded-bolted (HBB) joints. While load sharing in HBB joints is the crucial design parameter and it is important to capture strain field changes or failures under real-time loading conditions. Therefore, two-dimensional null digital image correlation null (2D-DIC) technique is applied to experimentally investigate the behaviour of bonded and HBB compo...

Abstract null null The bearing strength and failure behaviour of a new composite pre-tightened multi-tooth joint was studied experimentally and numerically. Four groups of different types of specimens were fabricated by varying key design variables including the pre-tightening force, tooth depth, tooth length, and number of teeth. Axial tensile tests were performed to determine the bearing capacity, failure modes, and load distribution law of the specimens. Furthermore, a three-dimensional conti...

Abstract The fracture failure of bonding structures is closely related to aging environment, so it is of great significance to study the effect of hygrothermal and alternating load coupled aging on bonding structures. Referring to the actual service environment of the vehicle, we formulated three kinds of artificial accelerated aging conditions, including temperature cycle, high temperature and high humidity and hygrothermal cycle. CFRP (Carbon Fiber Reinforced Plastic)/Al butt joints were selec...
