Dynamic characteristics of AS4/PEEK composites are investigated by the impact test and the sinusoidal free vibration test. Using a cantilevered beam with rectangular cross section, the natural frequencies and the damping properties are measured. The results for the specific damping capacity by the impact test are very close to those by the sinusoidal vibration test. The Youngs modulus by the impact test are slightly smaller than that by the tension test. The dynamic characteristics of angle-ply. cross-ply and quasi-isotropic laminates are computed by the first-order shear deformable theory. For the purpose of verification, experimental tests are carried out by the impact test for those laminates. The experimental values are very close to the theoretical values.
