Influence of Fiber Stacking Sequence in Inter-ply Hybrid Composites Structures on the Mechanical and Dynamics Properties

With the new manufactured methods developed in recent years, the application areas of layeredcomposite structures have increased considerably. In order to increase the utilization performances of thesestructures, hybrid composite structures were obtained by using single fabrics in different sequences. While manystudies have been carried out on the mechanical properties of layered hybrid composite structures, studies ondynamic properties are not enough. In the scope of this work, samples with 4 layers with 4 different sequencewere manufactured by using VARTM (Vacuum Assisted Resin Transfer Moulding) method using single glass (G4)and single carbon (C4) fibers. These samples are either single composite structures consisting of simple glass (C4)and plain carbon (K4) or symmetric composites with different order of arrangements of these two fibers within thesame structure (CGGC and GCCG). Samples were cut from produced composite sheets for three point bending,tensile and vibration tests according to the relevant ASTM standards. With three point bending tests determinedthe maximum flexural strength of the samples. Tensile tests were performed to determine the young modulus ofthe samples. In addition, natural frequency and damping ratio values were determined by free vibration analysisunder fixed-free boundary conditions. With the obtained results, the effect of sequence of interply hybrid compositestructures on the maximum flexural strength, the modulus of elasticity and vibrational properties was investigated.
