Vulcanization and the Properties of Rubber
Rubber is composed of long stringlike polymer molecules, which are pinned together at random points by crosslinks. As the density of crosslinks is increased, the molecules get localized and the system undergoes a phase transition from a liquid to an amorphous solid state. The elastic properties of the resulting solid are very different from those of metals, and are primarily due to changes in t...
متن کاملRubber friction and tire dynamics.
We propose a simple rubber friction law, which can be used, for example, in models of tire (and vehicle) dynamics. The friction law is tested by comparing numerical results to the full rubber friction theory (Persson 2006 J. Phys.: Condens. Matter 18 7789). Good agreement is found between the two theories. We describe a two-dimensional (2D) tire model which combines the rubber friction model wi...
متن کاملVulcanization characteristics and dynamic mechanical behavior of natural rubber reinforced with silane modified silica.
Two silane coupling agents were used for hydrolysis-condensation reaction modification of nanosilica surfaces. The surface characteristics were analyzed using Fourier transform infrared spectroscopy (FTIR). The vulcanization kinetics of natural rubber (NR) + silica composites was studied and compared to behavior of the neat NR using differential scanning calorimetry (DSC) in the dynamic scan mo...
متن کاملEffect of Rubber Nanoparticle Agglomeration on Properties of Thermoplastic Vulcanizates during Dynamic Vulcanization
We previously reported that the dispersed rubber microparticles in ethylene-propylenediene monomer (EPDM)/polypropylene (PP) thermoplastic vulcanizates (TPVs) are actually agglomerates of rubber nanoparticles. In this study, based on this new understanding of the microstructure of TPV, we further revealed the microstructure-properties relationship of EPDM/PP TPV during dynamic vulcanization, es...
متن کاملPerformance Matrix Based Contoller Tuning for Tire Vulcanization Process
Global competition today is forcing tire-manufacturing industries to implement continuous improvement systems that can reduce cost and improve product quality. Proportional-Integral-Derivative (PID) controllers play a key role in the quality of vulcanized tire. This paper presents a novel method for the performance assessment and controller tuning of temperature control loops in a tire vulcaniz...
