Numerical Modal Analysis of Adhesively Bonded Joints of Aramid Fiber Composites with Interply and Intraply Carbon Fiber Hybridization

Adhesively bonded joints are widely employed as components in a wide range of industrial applications. These joints can be subjected to quasi-static forces as well as dynamic loads. Therefore, the determination of the dynamic properties of these joints is very critical in terms of the strength and service life of the structure. In this study, previously manufactured and mechanically characterised aramid and carbon fiber reinforced composites were modelled as adherend components in joints and the effects of interply/intraply hybridization on the vibration behaviour of joints were investigated by finite element analysis (FEA). The first natural frequencies and mode shapes of the joints were obtained for three different boundary conditions (free-free, clamped-free and clamped-clamped). It was observed that the clamped boundary condition had a significant effect on the first natural frequencies of joints with intraply adhrends.
