EFFECTS OF ELEVATED TEMPERATURES ON THE THERMOMECHANICAL PROPERTIES OF A CARBON/GLASS-FIBER HYBRID COMPOSITE ROD
In the present paper,a carbon/glass-fiber hybrid composite rod developed for aluminum conductor composite core(ACCC),was studied on its thermomechanical properties exposed to elevated temperatures.The rods were subjected to 160 ℃ or 200 ℃ for 200 and 400 hours,respectively.The tensile property was tested at the elevated temperatures,or at the room temperature.As found,the tensile properties were slightly affected when the treated temperatures below the glass transition temperature(Tg)of the rod.When the treated temperature exceeding Tg,however,the mechanical properties was impaired dramatically.Serious thermal degradation of the resin matrix at elevated temperatures was attributed to the degradation of the composites.The compression and interlaminar shear properties degraded to a much higher degree compared to the tensile properties,since they are more dependent on the properties of the resin matrix.The dramatic decrease of the Tg of thermal aged composites indicated the molecular chain breakage of the resin due to the elevated temperature treatment..
