Alternative testing method for X-ray imaging sensitivity of composite materials

The invention belongs to a material detection technology, and particularly relates to an alternative testing method for the X-ray imaging sensitivity of composite materials. Although relevant provisions are made about a pattern and a specification of a used image quality indicator in GJB5364 Ray Real-Time Imaging Detection Method and GJB1038.2A Nondestructive Testing Method for Fiber Reinforced Composite Materials Part 2 X-ray Radiographic Examination, a composite material image quality indicator is difficult to machine due to special making processes of composite materials, the variety of components and the like; moreover, due to heterogeneity of the composite materials, no uniform composite material image quality indicator is made in China. By adopting an X-ray imaging sensitivity method capable of easily and rapidly testing the composite materials provided by the invention, the composite material imaging sensitivity can be tested effectively.
