The invention in particular relates to a nondestructive testing method of a carbon fiber composite multi-blade integral rotor, aiming at solving the problem that the existing nondestructive testing method has the defects. The method comprises the following steps: a. labeling blades on the integral rotor with numbers; b. selecting an X-ray three-dimensional (3D) detection device; c. adjusting a workpiece so as to enable the workpiece to be within the irradiation range of a ray beam and the receiving range of a receiving panel; d. adjusting the distance between the receiving panel and a ray tube and the distance between the workpiece to the ray tube; e. calculating the subsection positions of the workpiece; f. determining the transmitting illumination parameters of the thickest area and the thinnest area of the ray; g. removing the workpiece from the detection range and carrying out transmitting illumination; h. inputting the transmitting illumination parameters and the subsection positions of the workpiece into the detection device; i. setting a scanning way to be conical scanning; j. forming a final complete 3D workpiece figure; k. sectioning for carrying out defect evaluation and accurate measurement. The nondestructive testing method is high in efficiency and free from non-detection zone.
Description
technical field [0001] The invention relates to a non-destructive testing method, in particular to a non-destructive testing method for a carbon fiber composite material multi-blade integral rotor. Background technique [0002] Carbon fiber composite materials have been widely used in military and civilian fields due to their light weight, high specific strength, and corrosion resistance. The main component of the underwater vehicle propulsion device—the multi-blade rotor has also been processed and manufactured using carbon fiber composite materials. . [0003] After the carbon fiber composite multi-blade integral rotor is processed, in order to ensure its strength and reliability, non-destructive testing of its internal quality is required to determine whether it contains defects that affect its use (delamination, debonding, pores, inclusions, etc.) . [0004] For carbon fiber composite multi-blade integral rotors with complex structures and small spatial dimensions, the...
