Abstract

Aiming at the three-dimensional imaging of ceramic matrix composite (CMC) plate-like component, and the higher resolution imaging requirement of the local region of interest (ROI) in practical engineering applications, imaging experiment of CMC plate-like component was performed by the ROI computed tomography(CT), the resolution of CT imaging reached 28.4 microns, and three-dimensional(3D) imaging of the ROI in CMC plate-like component was realized. The characteristics of pores and typical weaving defects were analyzed from the three-dimensional structure, the three-dimensional morphology of internal pores and typical weaving defects were extracted and visualized respectively. The results show that the region of interest CT can meet the requirements of three-dimensional imaging of focus area of CMC plate-like component, and the 3D morphology, fiber weaving, pores and porosity of CMC plate-like component can be characterized, the porosity of ROI is about 13.23%.
