Zusammenfassung: | Multi-layered composites are used more often in different military applications as constructional materials and light armours protecting against fragments and bullets. Each layer of these materials has very different physical properties. Therefore they are difficult objects to non-destructive testing and making possible detection of subsurface defects of these materials. Typical defects of composite materials are delaminations, lack of adhesives, condensations and crumpling. A method that possibly can be used to non-destructive testing of this type of materials and detection of internal defects deploys infrared thermography. In order to determine the potential use of thermal methods the specialized software was developed for computing 3D (three-dimensional) dynamic temperature distributions in anisotropic six-layered solid body with subsurface defects. In this paper are presented results of simulation representing possibilities for the use of IR thermography methods to test such composite materials. |
