“…This increase is not statically significant but indicates that there was no appreciable change in the joints' structural performance. However, the load-displacement curves exhibit a bi-linear response, reflecting a change in stiffness, and this behaviour is consistent with other published works on similar adhesive joints [33,19]. The second region with a lower slope can be attributed to the plastic deformation of the adhesive.…”

Herein, we present a novel approach for damage sensing in adhesively bonded joints using a carbon nanotube single layer web (CNT-SLW) which marks a significant departure from the approach of dispersing CNTs within epoxy resins. In this work, a very thin, highly aligned CNT-SLW (densified thickness ~ 50 nm) with aerial density of 2.0 µg/cm 2 was horizontally drawn from a vertically aligned CNT forest, positioned over an adhesive film, which was, in turn, placed between two non-conductive composite adherents. This was followed by the application of heat and pressure to cure the adhesive. These joints were subjected to quasi-static and cyclic loading to investigate the damage sensing performance of a CNT-SLW. The CNT-SLW sensor, placed parallel to the load direction, exhibits remarkably high cyclic stability as well as exceptionally high sensitivity to damage initiation and accumulation. The resistance increase (∆R/R o % ∼1633%) is significantly higher than that of adhesive sensors with dispersed CNTs/graphene, reported in the literature. Morphological studies help to explain the sensing mechanism through interactions of the CNT-SLW with the evolution of micro-cracks. These results demonstrate the potential of

“…It was one T of adhesives used by Kelly to experimentally show that the judicious choice of the adhesive leads to a higher static and fatigue strength of HBB joints [8]. Similar conclusions can be found in [7,[9][10], while numerous published papers showed higher mechanical performances can be obtained with HBB joints such as in [11][12][13][14][15][16][17][18][19][20][21][22] for example.…”

“…It was observed that the failure load increase with increasing the ratio of overlap length to adherend thickness. Bodjona et al [56] reviewed the hybrid bonded fastening joints and their applications in composite structures covering the experimental research, an analytical and numerical model of both joints, the design and manufacture of hybrid bonded bolted (HBB) joints and the hybrid bonded pinned (HBP) joint as detailed in Table 4.…”

Composites have been used extensively in various engineering applications including automotive, aerospace, and building industries. Hybrid composites made from two or more different reinforcements show enhanced mechanical properties required for advanced engineering applications. Several issues in composites were resolved during the last few years through the development of new materials, new methods and models for hybrid joints. Many components in automobile are joined together either by permanent or temporary fastener such as rivets, welding joint and adhesively bonded joints. Increasing use of bonded structures is envisaged for reducing fastener count and riveted joints and there by drastically reducing assembly cost. Adhesive bonding has been applied successfully in many technologies. In this paper, scientific work on adhesively bonded composites and hybrid composites are reviewed and discussed. Several parameters such as surface treatment, joint configuration, material properties, geometric parameters, failure modes, etc. that affect the performance of adhesive bonded joints are discussed. Environmental factors like pre-bond moisture and temperature, method of adhesive application are also cited in detail. A specific case of adhesive joints in hybrid bonded-bolted joints is elaborated. As new applications are expanding in the field of composites joining and adhesive joints, it is imperative to use information on multiple adhesives and their behaviour in different environmental conditions to develop improved adhesive joint structure in mechanical applications.
