Abstract: Carbon-epoxy (CE) material has excellent structural properties owing to high specific modulus, high damping and low thermal expansions. In this study, CE shaft was made for the high-speed CNC grinding machines and the centrifuges. The one step composite shaft made of carbon fibers in epoxy matrix was manufactured with 16 layers having stacking angles [0°/90°/45°/-45°] 2S using filament winding process. The experimental set up was made for the static and dynamic analysis and performance characteristics of the CE shaft rotated in aerostatic conical journal bearing at high speed (10000-65000 rpm). The comparison of amplitude of vibration decides the maximum operational speed of the shaft with low vibration in aerostatic conical bearings.
