Several potential liner materials for HE projectiles were tested at high strain rates in compression. Both good and poor performing materials were tested to determine what properties were important for good performance. Cellulose Acetate Butyrate CAB, a good performer, flows at a very low pressure and maintains a thin film of material even when strained to the extreme. The poor performers tended to shatter at high strain rates, or, as in the case of polyethylene, required much higher pressures to initiate flow.
