Plastic bonded energetic materials

Henry Tan's picture

plastic bonded explosives are composites containing energetic grains, ranging in size from less than one to a few hundred micrometers, embedded in a matrix of high-polymer binder.

Henry Tan's picture

The flow stress and the modulus in simple compression increase with increasing confining pressure. Thus, these materials become stronger and stiffer with increasing pressure.

The failure process also changes with pressure. At atmospheric pressure, failure is primarily due to crack processes, while at elevated pressures failure is due primarily to plastic flow.
