Dynamic stability of the lattice structures in the manufacturing of carbon fiber/epoxy composites including the influence of damping properties

Cylindrical and conical composite lattice structures have been used extensively as load bearing structures, especially in the aerospace industry. Because of this, the dynamic stability of structures subjected to external loads is a critical structural problem in rocket design, pressure vessels, rocket motor cases, gas tanks and aircraft where pressure occurs. Elastic instability will cause buckling and eventually lead to catastrophic failure of the structure. The purpose of this research was to investigate the dynamic conditions and behavior of lattice cylinders manufactured from carbon fiber/epoxy composites. Also, our task was to evaluate the force and free vibration including non-elastic resistance and damping properties, the variable parameters and strength characteristics of carbon fiber. Additionally, the mechanical vibration the lattice structures was calculated and to create a system which was able to register of the force frequencies and reduce the free vibration due to the maintenance of the appropriate electrical circuit. Additionally transform electrical signals to ultrasound signals, which are beneficial to avoid parametric resonance.
