Outline of Final Research Achievements |
Residual stresses in the carbon fiber and the polyamide matrix of CFRP composites were measured by the x-ray stress measurement method. In this study, a transmission method of x-ray diffraction was employed for the residual stress measurement of the sin^2psi method. The transmission method enabled to estimate the stress measurement used low angle diffraction peaks. Many stable results were obtained from these new trials. It was succeed to estimate residual stresses in the CFRP pipe and plate by this method. Furthermore, the in-situ residual stresses measurement in the very low temperature is tried using a cryostat system. However, there is a problem in the sample cooling conditions. This is an unexpected phenomenon, and it is under investigation to determine the cause.
