In a systematic study on the mechanical and dielectric properties of styrene-butadiene rubber (SBR) reinforced with polyester short fiber (PE), the effects were studied of adhesion system HRH (hydrated silica, resorcinol and hexamethylene-tetramine), fiber concentration, semireinforcing furnace carbon black (SRF) and thermal aging on these properties. The permittivity ε' and the dielectric loss ε'' for the samples under test were determined in the frequency range 100 Hz to 10 MHz. It was found that the addition of the tricomponent adhesion system HRH to SBR-PE vulcanizates improves the mechanical and dielectric properties. Also, the increase of short fiber concentration in the SBR vulcanizates in presence of the adhesion system improves the mechanical properties. The addition of SRF carbon black facilitates the compounding of PE with SBR; moreover the tensile strength, Young's modulus and the permittivity were increased while the elongation at break was decreased. The samples under test were subjected to thermal aging. The mechanical and dielectric properties were then reinvestigated and the data obtained interpreted. |
