The subject of this paper is the fracture characteristics of single particles of polymethylmethacrylate (PMMA) or polystyrene (PS) when they were impacted on a target by using an air gun. As a result of experiments a new method of measuring the specific fracture-surface energy was also obtained.<br> From the total energy balance of the impacted particle and the target, the specific fracture energy for PMMA and PS was calculated from four kinds of measured values, namely impact velocity, rebound velocity, deformation, and impact force of a collided particle. The specific fracture energy was formulated as a function of the impact velocity of a particle.<br> The specific fracture-surface energy was also calculated from the values of the specific fracture energy and the increase of specific surface area. The values of the specific fracture-surface energy at the optimum impact velocity were estimated to be 1.5-2.0 kJ/m2 for PMMA and 3.0-3.4 kJ/m2 for PS.
