气体比重瓶法测定碳纤维密度试验方法的研究

Research on the Test Method for Determining Carbon Fiber Density by Gas Pycnometer

通过研究在不同样品量、不同温度和不同前处理方式下使用气体比重瓶法测定碳纤维密度的试验,分析不同因素对气体比重瓶法测定碳纤维密度结果的影响,为修订ISO 10119《碳纤维密度的测定》国际标准提供了依据。同时通过组织不同实验室间的循环比对试验,分析证明气体比重瓶法的可靠性和准确性。

The influences of different factors on the results of determining the density of carbon fibres by gas pycnometer method were analyzed by studying the tests using different sample size,temperature and pretreatments,which provided a basis for revising ISO 10119 Carbon fibre—Determination of density.In addition,the reliability and accuracy of the gas pycnometer method were demonstrated by organizing round robin tests between different laboratories.
