Abstract:
In the current study the effect of nanoclay content and carbon fiber orientation on the buckling properties of epoxy/nanoclay/ carbon fiber orientation is investigated. Buckling samples were prepared with 1, 3 and 5 wt% of nanoclay and 0, 30 and 45 degrees of fiber orientations based on VARTM technique. The results obtained from the buckling tests showed that adding 1wt% of nanoclay into the pure epoxy in different fiber orientations decreased the magnitude of critical buckling loads and the stress of starting the buckling process. Furthermore, in a constant fiber orientation, increasing the weight percentage of nanoclay increased the magnitude stress of starting the buckling process and the critical buckling load and then decreased them. Moreover, in-creasing the degree of fiber orientation decreased the buckling loads properties generally. The maximum values of stress of starting the buckling process and critical buckling load were 68.16 Mpa and 3.697 kN respectively which occurred with 3 wt% of nanoclay and 0 degree of fiber orientation.
