Abstract
According to GB/T 22588-2008,Determination of thermal diffusivity or thermal conductivity by the flash method.and JJF 1059.1-2012,Evaluation and expression of uncertainty in measurement,the uncertainty of thermal conductivity of pitch-based carbon fibers was measured.Through analysis,it was found that the main sources of uncertainty were sample density,specific heat capacity of the sample,thermal diffusivity of the sample,repeated tests,indication errors and data correction.Finally,the uncertainty of a pitch-based carbon fiber was determined to be 17 W/(m·K)when its thermal conductivity was 600 W/(m·K).关键词
