SPEAKER: Seiichi Kawahara, Nagaoka University of Technology ABSTRACT: Effects of nanodiamond on the mechanical properties of natural rubber were investigated by forming nanomatrix structure in the rubber. Natural rubber with the nanodiamond nanomatrix structure was prepared by chemical reaction of the rubber particles with nanodiamond in latex stage followed by drying. Dynamic mechanical analysis, differential scanning calorimetry, transmission electron microscopy were carried out for natural rubber with the nanodiamond nanomatrix structure. Energetic elasticity in conjunction with the entropic elasticity were investigated in relation to bound rubber between natural rubber and nanodiamond. A significant increase in complex modulus for natural rubber with nanodiamond nanomatrix structure was attributed to the complex modulus of the bound rubbers.

Intrinsic Strength and Tearing Behavior of Tread Rubber Compounds
Open to view video.
Open to view video. SPEAKER: Nihat A. Isitman, Goodyear Tire & Rubber Company ABSTRACT:While a number of studies discuss the ultimate tearing behavior of unfilled rubber compositions and how it is influenced by basic formulation variables, for instance, the choice of elastomers, crosslink density or the nature of crosslinks, there is limited understanding of how those ingredients influence threshold energy (T0), crack propagation rate and critical tearing energy (Tc) for high loading levels of silica in tire tread compounds. This research investigates the effects of basic formulation variables in filled model tread rubber compounds on general tearing behavior using a variety of techniques such as intrinsic strength analysis to determine T0, cut growth analysis to establish crack growth rate as a function of tearing energy, and planar tension (pure shear) tear testing to obtain Tc. The strain and temperature dependent viscoelastic properties will be discussed considering that the tearing behavior at the crack tip zone is influenced by dissipation characteristics. The talk will elaborate tearing behavior of model rubber compounds in relation to polymer blend composition, crosslink density and silica loading.
