The Effect of Different Adhesive Types on Failure Load

In this study, bonding joint with double zigzag type geometry was used. There are four types of overlap angles in the bonding geometry: 30°, 45°, 60° and 75°, respectively. Composite materials that are made of glass fiber have been used in this adhesive bonding geometry. These materials were produced by using prepreg (pre-impregnated) technique and [0°/90°] of orientation angle. Thickness of composite material is 3 mm. Ductile and brittle-type adhesives were used for the bonding joint. DP460 adhesive type shows ductile material properties while ATLAC580 adhesive type shows brittle material properties. The effect of adhesive type on the failure load was investigated experimentally. Test results demonstrated that failure load values were higher in the ductile-type adhesive
