Nowadays, the demand for carbon-boron boron-based composites has tremendously increased in the aerospace and automotive industries due to their lightweight and high strength-weight ratio. Hence, it is necessary to study the vibrational behavior of the carbon-boron matrix. The stacking sequences, fiber orientation, crack size, and length-width ratio has all been studied at three levels. A mathematical model has been developed using classical laminated plate theory to evaluate the natural frequency for two boundary conditions; first, all sides were supported (SSSS), second, two adjacent sides clamped, and the other two were simply supported (CCSS). Grey relation analysis has also been applied to optimize the parameters.
