Abstract
Most textile composites are anisotropic materials, and their mechanical properties strongly depend on the fiber orientations in the preforms after forming process. In order to guarantee that the fiber orientation of the preforms meeting the requirements of product design, at present, many nondestructive testing technologies have been employed for textile composite preform forming process and quality detection. In this paper, combines with the development trends of textile composite preform preparing technology and nondestructive testing technology requirements on preform forming process, a variety of nondestructive testing technologies which are widely used in scientific research and industrial production are reviewed, including contact measurement technology, optical testing technology, thermography testing technology, eddy current testing technology and radiographic testing technology. The technical characteristics, application and existing problems of each method are summarized. Finally the development trend and the challenges of nondestructive testing technologies for textile composite preform forming process are discussed.
