A new machine and method for testing a series of friction factors between Energetic Materials with rubbers and some material was reported in this paper.The relations between friction factor and H50 was also explored,the principle and results of the test of friction factor among plastic,rubber and explosive were reported.Using the instrument,assigned mainly to test the frictionfact between plastic,rubber and explosive and to test the frictional temperature,test the friction factors.The instrument consisted of a normal pressure sensor and a moment of torsion sensor,mechanical system and a velocity adjustable system.The measure extend of the pressure sensor was 0~300kgf and 0~2N.m for the moment sensor.The relative precision of them is 5‰.
