Four polymeric powders, ranging in average particle size from 75 to 170μm, were shock consolidated at pressures between 6.5 and 14 GPa. High green densities of the order of 95% of theoretical were obtained as a result of plastic deformation, particle comminution and interparticle bonding. Compressive strength to fracture of up to 60 MPa was attained and satisfactory post‐shock creep properties were noted. Explosive compacating parameters are discussed and related to impact and material characteristics of direct, axisymmetric systems.
