摘要
Disclosed are a method for evaluating a local density profile in a carbon/carbon material and a method for producing a standard density test block capable of quantitatively evaluating the density profile in the carbon/carbon material, wherein the method for evaluating the density profile includes a first step of preparing a standard density test block to be inserted in the carbon/carbon material, wherein the standard density test block is produced by using the same type of material as the carbon/carbon material and thereafter inserted in the carbon/carbon material, a second step of radiating X-rays onto the carbon/carbon material having the standard density test block inserted so as to obtain and correct computed tomographic image, and a third step of measuring a physical density by use of a linear attenuation coefficient of the computed tomographic image, whereby the local density profile can accurately be evaluated by use of a nondestructive testing and additionally such method can be utilized as an excellent means for improving processes and ensuring quality.
