Study on the Impacting Thermal Effects of PTFE/Al Energetic Materials

Abstract

To study the temperature variation of Polytetrafluorethylene/Al (mass ratio 73.5/26.5) energetic reactive material under impact loads, using the ANSYSAUTODYN to carry out numerical simulation for its temperature changes when penetrating 45 steel target. Through the analysis of the temperature change which occurred on the gauge, it shows that with the increase of penetrating velocity, the temperature of energetic material nonlinear rises. Numerical simulation also shows that when the velocity is lower than 1200m/s, the maximum temperature of energetic materials is in the head, above this velocity in the middle. Literature results validate the simulation is reasonable.
