Abstract
During in our research work we examine the condition of developing elastomer – metalconnection at manufacturing machine – and car industry hybrid parts. As a first step we have carried outcomparison tests relating to the strength properties of synthetic – and natural rubber mixtures. During testswe have compared four mixtures used often in the practice (NR, NBR, EPDM, CR) in three characterichardnesses (43 Sh0, 57Sh0, 72Sh0). In addition to hardness we have measured the elongation at ruptureand the density, too. As a continuation of our tests we researched what connection is between the surfaceroughness of metal plate and the elastomer – metal bonding formed.
