Abstract
Polymer-bonded explosives (PBXs) came into being and are widely used as energetic fillings in many systems as they are more chemically and mechanically stable than traditional ones. There are three kinds of materials named by PBX1, PBX2 and PBX3, the last two of which are newly invented. To investigate the mechanical properties of newly manufactured PBXs, we carried out the dynamic compression tests as a function of strain rate and temperature with Split Hopkinson Pressure Bar (SHPB). The experiment temperatures were set to be 25°C, 50°C and 65°C. The constant strain rate is assured by using brass as a pulse shaper, and as for brittle materials, the constant loading strain rate is limited at about 550s-1. The results show that the compressive strengths and moduli of each material decrease with increasing temperature and increasing with increasing strain rate. Failure is by brittle fracture for each condition and the cracks’ major axis makes an angle of 30° with the direction of the applied stress.
