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...

Tires

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...

Polystyrene-Butadiene grafted Imide-Imine for Enhancing Adhesion between Rubber and Polypropylene fibers

Acrylic acid reacted with ethylene diamine to give amide- imine oligomer. This oligomer was grafted to polystyrene-butadiene rubber. The oligomer structure was elucidated using FT-IR, 1H- NMR, 13C-NMR and mass spectroscopy. more...

EPDM waste rubber

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...
