| Abstract: |
| The effect of aramid pulp on physical properties，microstructures and low temperature
resistance of carbon black N990/fluoroether rubber composites was studied to provide reference for the
development of high performance fluoroether rubber composites.The results showed that there was no
significant change in the vulcanization characteristics and dynamic mechanical properties of the fluoroether
rubber composites with addition of 1 phr non-heat-treated aramid pulp and heat-treated aramid pulp.The
modulus at 100% elongation，modulus at 300% elongation，tensile strength and tear strength were increased.
The dispersion of heat-treated aramid pulp in the rubber matrix and the interfacial adhesion with the rubber
matrix were better，and the reinforcement effect of fluoroether rubber composites was more significant.
Addition of 1 phr non-heat-treated aramid pulp and heat-treated aramid pulp had little effect on low
temperature resistance of fluoroether rubber composites，and could improve their physical properties of
fluoroether rubber composites while maintaining the good low temperature resistance. |
