Stability of Hybrid Composite Plates with Cut-out 2021-28-0176
Composites being high in strength to weight ratio is preferred for automobiles. Hybrid Composites due to its fatigue resistance, low cost and reduction in notch sensitivity makes it eligible for application in automotive industry. Hybrid composites are used in automotive anti roll-bar, brake friction material and pistons and strut bars. Carbon epoxy being costly is reinforced with glass epoxy to achieve the desired effect of weight reduction along with saving the cost. In paper focus on stability analysis of hybrid composite plate with elliptical cut-out is studied. The edge condition of simple supported on all boundaries is utilized for analysis. The effects of major axis, minor axis and area of elliptical cut out, for hybrid as well as for single laminate of carbon epoxy is being studied. Comparisons of perforated and non-perforated conditions are studied and accordingly results are obtained.
