Abstract : Two problems were studied. These were (1) the Hugoniot equation of state of carbon phenolic with two different initial internal energies and (2) the effectiveness of polyurethane foams in reducing peak pressures induced in plate slap experiments. Measurements were performed on unheated samples of carbon phenolic at 23o and on preheated samples at 150o; attenuation rate of shock waves traversing the material and the tension at which the material failed were determined at the two temperatures. In addition several series of experiments were carried out to investigate the phenomenon of non-hydrodynamic attenuation. (Author)
