Low strain rate (10{sup {minus}3} to 10{sup {minus}1}s{sup {minus}1}) compression measurements have been obtained on three different composite materials: PBXN-9, PBX 9501, and a 9501 sugar mock. These measurements expand on earlier efforts to identify the behavior of PBX 9501 and sugar mocks at different rates, sample aspect ratios (L/d) and temperatures. PBX 9501 samples at three different L/d{close_quote}s were strained at the same strain rate to evaluate L/d effects on the stress-strain parameters. PBXN-9 data were obtained at two different L/d{close_quote}s, two different temperatures, and at three different rates. The PBXN-9 data exhibit similar trends to other energetic materials data, i.e. 1)increased ultimate compressive strength and modulus of elasticity with either an increase in strain rate, or decrease in temperature, and 2)small increases in the strain at maximum stress with decreases in temperature or strain rate. A comparison of the PBXN-9 data to the PBX 9501 data shows that both begin to fail at comparable strains, however the PBXN-9 data is considerably weaker in terms of the ultimate compressive strength. {copyright} {ital 1998 American Institute of Physics.}
