The Dynamic Behaviour of Symmetrical Laminated Nano-composite Containing Equal Numbers of Glass and Carbon Fibre Layers

Fibre-reinforced polymer composite has many uses in structural components that required high strength, stiffness, and damping capacity. Cross quasi-laminated epoxy composites with without nano Al2O3 were used this investigation to determine flexural modulus, natural frequency, ratio, mode shapes by using analytical, experimental, numerical (ANSYS) methods. It was demonstrated adding 2 % improved the modulus ratio while decreased frequency. number quasi had highest frequency for cross laminate groups which are equal 23.5 Hz 20.25 experimentally, respectively. On other hand, higher achieved 1 both laminates, 0.707 0.693 %, The inversely related each other. However, novelty article is two glass plies at outer surface of group increased simultaneously, as configurations comparison Al2O3.
