Abrasion resistance of silica filled passenger car tire tread compounds

Void Volume Measurement – an alternative Approach to Determine the Initial Structure of Silica

To improve the abrasion resistance of silica filled passenger car tire tread compounds a good dispersion and distribution of the silica in the rubber matrix is required. From the literature it is known that the structure of fillers affects the dispersion process. more...

Rubber Suspension in Sports

“Rubber” an indispensable Material for high Performance in Sports Application

The present paper deals with the development of a progressive rubber-suspension system as light weight construction substituting a combination of a steel spring and rubber bushing system for sports equipment application. The new developed rubber suspension element uses the V-element geometry with respect to well-known non-linear mechanical behaviour of rubber and the expected non-linear relationship […] more...

Prediction of Elastomeric Properties

A Proposition of constitutive Relationship of isotropic incompressible hyperelastic Material with limited Extensibility on the Basis of Gent’s Model

Elastic properties of rubber-like materials with limiting extensibility can be characterized by means of strain energy function and locking condition. One can show that the Gent’s model cannot be used for relatively large stretches and provides poor approximation of experimental data. The basic aim of the present paper is to propose a generalization of Gent’s […] more...

Simulation of Tire-Road static Interaction of all-Steel Pneumatic Truck Tire

A source of the specific properties of the cord-rubber tire composite and difficulties encountered in the analysis of deformation of a pneumatic tire are pointed out. A method is proposed for modeling of deformation of the tire that provides valuable results from the tire designer’s point of view. As a result of simulation of the […] more...

Recycling of EPDM Rubber Waste Powder by Activation with liquid Polymers

The recycling of ethylene-propylenediene- rubber (EPDM) waste was realized by activation of EPDM rubber waste particles surface with liquid EPDM polymers (LP) of low molecular weight. The optimal ratio of the waste EPDM rubber to LP was investigated whit regards to the original EPDM properties. more...
