520 | |a The high temperature caused by current-carrying wear could affect the thermal reliability of resin-based contact strip greatly. This study adopted liquid-phase impregnation-carbonization (IC) technique to improve the thermal stability and densification of carbon fiber reinforced contact strip (CFRCS). The influence of this method was investigated by scanning electron microscopy, Fourier transform infrared spectrometry, thermal gravimetric analysis and energy-dispersive spectrometry; meanwhile, specimen composition and friction and mechanism properties were also analyzed. The results show that heat treatment is helpful in improving the material’s temperature tolerance. When specimens undergo IC treatment four times, resistivity and wear rate would reduce gradually under impregnating conditions of carbonization temperature (800°C), dipping liquid concentration (60%), and dipping temperature (60°C). IC treatment is effective in reducing material porosity and improving the impact resistance performance compared with only carbonized sample. Densification treatment can also improve the samples’ compressive strength and bending strength. The main wear mechanisms of CFRCS-25 and CFRCS-800 against copper with electrical current are similar; these are arc erosion wear and oxidation wear accompanied by adhesive wear. Adhesive wear and oxidative wear is more severe for CFRCS-25 than CFRCS-800. | ||

Densification treatment and properties of carbon fiber reinforced contact strip |
abstract |
The high temperature caused by current-carrying wear could affect the thermal reliability of resin-based contact strip greatly. This study adopted liquid-phase impregnation-carbonization (IC) technique to improve the thermal stability and densification of carbon fiber reinforced contact strip (CFRCS). The influence of this method was investigated by scanning electron microscopy, Fourier transform infrared spectrometry, thermal gravimetric analysis and energy-dispersive spectrometry; meanwhile, specimen composition and friction and mechanism properties were also analyzed. The results show that heat treatment is helpful in improving the material’s temperature tolerance. When specimens undergo IC treatment four times, resistivity and wear rate would reduce gradually under impregnating conditions of carbonization temperature (800°C), dipping liquid concentration (60%), and dipping temperature (60°C). IC treatment is effective in reducing material porosity and improving the impact resistance performance compared with only carbonized sample. Densification treatment can also improve the samples’ compressive strength and bending strength. The main wear mechanisms of CFRCS-25 and CFRCS-800 against copper with electrical current are similar; these are arc erosion wear and oxidation wear accompanied by adhesive wear. Adhesive wear and oxidative wear is more severe for CFRCS-25 than CFRCS-800. |

This study adopted liquid-phase impregnation-carbonization (IC) technique to improve the thermal stability and densification of carbon fiber reinforced contact strip (CFRCS). The influence of this method was investigated by scanning electron microscopy, Fourier transform infrared spectrometry, thermal gravimetric analysis and energy-dispersive spectrometry; meanwhile, specimen composition and friction and mechanism properties were also analyzed. The results show that heat treatment is helpful in improving the material’s temperature tolerance. When specimens undergo IC treatment four times, resistivity and wear rate would reduce gradually under impregnating conditions of carbonization temperature (800°C), dipping liquid concentration (60%), and dipping temperature (60°C). IC treatment is effective in reducing material porosity and improving the impact resistance performance compared with only carbonized sample. Densification treatment can also improve the samples’ compressive strength and bending strength. The main wear mechanisms of CFRCS-25 and CFRCS-800 against copper with electrical current are similar; these are arc erosion wear and oxidation wear accompanied by adhesive wear. Adhesive wear and oxidative wear is more severe for CFRCS-25 than CFRCS-800.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">carbon fiber</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">contact strip</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">impregnation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">resistivity</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">wear mechanism</subfield></datafield><datafield tag="653" ind1=" " ind2="0"><subfield code="a">Materials of engineering and construction.
