Rotordynamic experiments are performed on two hollow tubular Carbon/Epoxy filament wound composite shafts. The experiments comprise of determination of critical speed and unbalance response as well as orbital and spectrum analysis. Step-wise progressive balancing near the critical speed was needed to operate the shaft in the super-critical region. Critical speeds determined from experiments match extremely well with theoretical values obtained from the equivalent modulus beam theory.
