摘要
Using a specially designed apparatus simultaneous measurements were carried out of the area of contact and the friction between elasstomers and solid surfaces. For a wide range of load, the friction force is proportional to the actual solids. In the range of low sliding velocities the actual contact area remains almost constant. At high sliding velocities increase of the friction force is associated with the process of the mechanical glass-transition of the surface layer of the crosslinked rubber which causes the actual contact area to decrease.
