Overview
Background & policy context:
The addition of nanoparticles in rubber tire tread is essential to improve the wear properties of the material but leads to an increase in rolling resistance. The substitution of carbon black by silica allows to limit the rolling resistance and the performances of the system are controlled primarily by two parameters:
- The Dispersion of the filler
- The load-polymer interface
The problem is that these two parameters are not independent and the dispersion is difficult to measure in industrial systems due to nanoparticles fractality.
Objectives:
The objectives of this project were therefore multiple:
- Study of a model where the particle dispersion system is measurable => elastomers reinforced with spherical silica;
- Comparison with a 'real' system;
- Better understand how to modulate the different system parameters in order to obtain materials with perfectly controlled properties.
