nature : Objects can be extended resistance, compression and bending deformation of a performance. Determination of rubber flex fatigue resistance, is a cylindrical test unit installed in flex fatigue test machine, this test must then wrapped tablets radian, side force and elongation, the other side is compression. Then activate the test equipment so that rotating the idea. As many turn elongation and compression, the test piece due to stress and dynamic fever, fatigue damage gradually. Records fracture of time or frequency of rotation, and to measure its internal temperature increases, namely, the material flex fatigue resistance properties. Damage to the longer time required, the lower the internal temperature rises, the better material durability.
