| Abstract: |
| The work aims to study the aging mechanism of camouflage materials in the practical period, and learn the main environmental factors of the failure of camouflage materials. The main factors affecting the aging failure of camouflage materials were obtained by analyzing the performance changes of camouflage materials in natural environment and laboratory single factor environment. Scanning electron microscope (SEM), infrared spectrometer and X-ray photoelectron spectroscopy were used to characterize the changes in the microstructure, chemical structure and chemical composition of the materials, and to explain the aging mechanism of the camouflage materials. The color, appearance and mechanical properties of the camouflage materials under different natural environments and single factor environment in laboratory were obtained. The changes of microstructure, chemical structure and chemical composition of camouflage materials during aging were obtained. The aging degree of camouflage materials in Xishuangbanna is the highest and the aging degree is the lowest in Jinan natural environment. Illumination is the main factor that leads to the decline of color and mechanical properties of camouflage materials. During the aging process, the main reason is that the polyurethane on the surface of the material becomes aged and comes off, which leads to the decline of the mechanical properties of the material. When the camouflage materials are damaged, the fiber failure forms are as follows:one is the fiber direct fracture and the other is that the fiber is pulled out, or breaks during pull-out. |
