Fatigue, Fracture and Wear Properties of Rubber

Abstract

Characterizing the fracture properties of technologically important elastomers (non-linear, non-elastic materials) has been uncertain because of the extensive energy dissipation during deformation. The objective of the research was to evaluate the J-integral concept of fracture as a fracture characterizing parameter and to relate the fracture resistance to crack tip microstructure in carbon black filled natural rubber. Wear rate of rubber, thought to be primarily related to fracture resistance, was studied and correlated by fractal analysis to the wear surface. Fracture was characterized by the J-integral and carbon black increased fracture resistance by increasing strain induced crystallization. The research results as published papers are included. Keywords: Carbon black reinforcement, Fatigue, Fractal analysis, Fracture, J-Integral, Strain induced crystallization, Wear.
