“…For the past few decades, the joining techniques used were adhesive bonding, bolt fastening, and adhesive-bolt hybrid joining; this has led to various researches studies on the combination of dissimilar materials and the joining methods [5]: single-lap [6], double-lap [7][8][9], scarf [10,11], strapped [12,13], and tapered joints [6]. The mechanical fastening methods riveting, screw-type fasteners, washers and bolt and nut were used in the bolting condition and always required drill holes on the substrates.…”

“…The adherend and adhesive were glued together using Boolean operation. The meshing in adhesive region was performed in a more sensitive manner by dividing it into small pieces , Figure . In order to perform the stress analysis of the adhesive, elements at adhesive region and at the overlapping planes have been prepared with high density; and elements of outside parts of adhesive regions have been prepared with low density.…”

In this article, the tensile strength of different adhesive bonded joints under a tensile load was analyzed numerically. The effects of certain parameters, including the bonding length and bonding ratio, were investigated. For this reason, the epoxy adhesive was used. Joints were prepared with aluminum materials. The stress analyses were employed using the Finite Element Method (FEM). ANSYS (v.14.0.1) FEM tool was utilized to investigate the stress distribution characteristics of aluminum lap joint under tensile loading. Numerical results were found to be quite reasonable. The numerical results show that the influences of variations are very notable when the equivalent stresses are between 18 MPa and 20 MPa.

“…Many investigators studied the effect of bond line thickness on the strength of bonded joints/repairs [15][16][17][18][19][20][21][22][23]. Xiaoquan et al [17] showed that when the adhesive film thickness is about 0.15-0.25mm, the ultimate stress of the scarf repaired plate reaches the highest value.…”

“…Xiaoquan et al [17] showed that when the adhesive film thickness is about 0.15-0.25mm, the ultimate stress of the scarf repaired plate reaches the highest value. Bond line thickness ranging from 0.2 to 0.25 mm is recommended by some researches [15,19]. Therefore, in the present work bond line thickness of 0.25 mm was adjusted for all the test samples.…”

Epocast 50-A1/946 epoxy was primarily developed for joining and repairing of composite aircraft structural components. The Epocast epoxy was modified by ultrasonic dispersion of Multi-Walled Carbon Nanotubes (MWCNTs) with different weight percentages. Neat epoxy (NE) and the optimum MWCNT weight percentage are used to fabricate structural adhesive joints (SAJs) with different scarf angles (5 o , 10 o , 15 o , 30 o , and 45 o) in carbon fiber reinforced epoxy (CFRE) composite adherends. SAJs with different scarf angles were instrumented by eight strain gauges to measure the adherend tip strains and bond line strains during tension tests. The effect of water absorption on the tensile properties of the SAJs with 5 o and 10 o scarf angles was investigated experimentally. Because the SAJs with 5 o scarf angle have the highest tensile properties, special attention was considered to investigate their performance under elevated temperature (50, 75 and 100 o C) and fatigue loads. The tensile properties of the MWCNT/E-SAJs showed significant improvements compared to the neat epoxy-SAJs. Crack initiation and propagation were detected effectively using the instrumented-SAJs. The effect of water absorption has marginal effect on the tensile strengths of the SAJs. On the other hand, the tensile strengths and stiffness are dramatically decreased at elevated temperature. MWCNTs have insignificant effect on the fatigue lives of the SAJs.
