“…For the higher 0 layers' combination percentage case, the grouping of similarly 0 oriented plies leads to the generation of bigger fragments, which contributes to the formation of a pack of material and thus delivers the damage development on a more significant part of the specimen. 26 This leads to an earlier composite damage loss and lowers the 2% offset bearing strength. In contrast, the 0 layers' combination percentage has no effect on ultimate bearing strength of bearing specimens with fastener fracturing.…”

Considering the fact that the foundation data for a new X850 ± IM190 carbon/epoxy material system adopted in commercial aircraft industry are extremely scarce in the literature, an in-plane, static tensile experiment was carried out to investigate the bearing performance of double-lap, single-bolt joints in X850 ± IM190 carbon fiber-reinforced polymer (CFRP) composites. The effects of ply ratio, 0° layers’ combination percentage, bolt diameter, and curing method were considered. Then, special attention was paid to determine the design parameters of X850 ± IM190 CFRP bolted joints, such as tensile strength of un-notched laminate and stress concentration relief factor. Based on these design parameters, an efficient semianalytical approach was established to obtain the ultimate bearing strength of the joints. The failure prediction exhibited excellent agreement with the experimental data. These results will play an important role in design and strength evaluation of X850 ± IM190 CFRP bolted joints.

“…These forces can be separated in two components: a tangential one, mainly caused by hogging and sagging, and a normal component related to the structural stiffness of the connection. For this application, aluminum has a low fatigue resistance due to the stress concentration in the riveted joints, in addition to the risk of galvanic corrosion when contacting steel rivets [6][7][8].…”

“…Hart-Smith 13 studied various parameters of bolted connection and found that changing geometry parameters and bolt rows can change the failure mode and the bearing capacity. Park 14,15 experimentally studied the effects of stacking sequence and clamping force on bearing strength and failure mode of mechanically fastened joints in composite laminates. Rosales-Iriarte et al 16 and Choi et al 17 found that imposing a preload on composite laminates through bolts can improve the connector's ultimate bearing capacity and affect its failure mode.…”

Due to the insufficient connection efficiency of the bolted connection of pultruded composites, a novel composite connection technique called hybrid bolt-tooth connection was proposed. The paper presents a series of experiments studying the bearing capacity and the failure mode of the hybrid bolt-tooth connection by comparing with the pure bolted connection. Furthermore, the influences of the depth, the length and the number of the teeth on the connector's failure mode and bearing capacity were studied. The results indicate that compared with the pure bolted connection, the hybrid bolt-tooth connection has a higher connection efficiency thanks to the load sharing of the teeth. The number, the depth and the length of the teeth exhibit a significant influence on the bearing capacity and failure modes. With the increase of the number and the length of the teeth, the bearing capacity is improved effectively; the bearing capacity of the connection with shallow teeth is significantly higher than that with deep teeth. Therefore, the hybrid bolt-tooth connection is an effective jointing method and has a good application prospect.
