Carbon reinforced composites are extensively used in the structures like aircraft structures as there stiffness and strength are high with lower weight. Aircraft consists of different composite components they are empennage, parts of fuel and wings. Typical structures are wings ribs and intermediate spars, which can be built of CFC. Structures are introduced with the cut outs for lightening the components. Stress concentrations are determined for the introduction of holes. Therefore it also leads to lowering of the buckling load carrying ability. To decrease the stresses in the vicinity of the hole and to enhance the buckling loads there is a requirement of reinforcement of the holes. Here the consideration of the study containing a reinforced circular cutout in which a shear loaded square panel representing a segment of a composite (T300/976) rib. The effect of various reinforcement parameters is precisely included for both strength and stability.
