Vulcanized
rubber which is commonly used for vehicle tire material is generally in the
form of compound rubber derived from pure rubber reinforced with carbon black
and silica. Based on hardness, there are 3 types of compounds on the market,
namely hard, medium and soft. This study only discusses the performance of hard
compound, soft compound and as a comparison, rubber for carpet materials. The
performance that is very important to analyze is the tribological properties of
rubber, namely contact capacity and abrasion resistance. For applications in
vehicle tires, contact capacity is related to braking capacity while abrasion
resistance is related to the age of the tire. The tensile test is carried out
first to determine the strength of the material, then the tribological test is
carried out using a pin on disc type tribometer. The tribological test was
carried out with variations of the indenter (pin), namely ball indenter and
blade indenter types with load variations up to a certain number of revolutions.
Tests were carried out to find the friction coefficient and rubber wear level
during the abrasion test. In general, hard type vulcanized rubber has better
abrasion resistance than soft type. But on the other hand, the hard type of
vulcanized rubber has a lower friction coefficient or capacity than the soft
type.
