Abstract
This study used (U)SAXS to investigate how filler hierarchical structures and cavitation properties change under strain in rubber compounds with different silica content. The results were then compared to the macroscopically observed crack behavior of the samples. A critical threshold was identified around 21 vol.% of silica. The combined mechanical tests and (U)SAXS analysis revealed that increasing silica concentration accelerates cavity formation and crack propagation, most likely due to the amplification of local stresses, ultimately leading to premature compound failure. These findings highlight the importance of optimizing silica content to enhance the mechanical stability and longevity of rubber compounds.
