A scanning acoustic microscope (SAM) has been used to investigate the structure of thermoplastic leather. This material is formed by pressing fibers of leather under high pressure and moderate temperature. The result is a matrix from transformed, melted fibers in which leftover fibers act as reinforcement. Unlike the scanning electron microscope (SEM), the SAM is able to distinguish between completely and incompletely transformed fibers and also to penetrate the material beneath the surface. The results show that the matrix is built as a domain structure. The advantages of the SAM over the SEM for organic materials are indicated.

Infrared thermal wave detection technology has been found to be a new type of wide attention non-destructive testing (NDT) method due to its non-contact, non-destructive, rapidity, wide imaging field and advantages of direct observation. Key technologies and the latest research progress of the infrared thermal wave technology in parts defects are reviewed in this paper. The key technologies include the heat stimulator, infrared thermal image processing, heat transfer analysis and etc. The existing problems of the technology are also pointed out.
