| titleOfInvention | A fluorescence detection method for interfacial debonding of fiber-reinforced polymer composites |
| abstract | The invention discloses a fluorescence detection method for interfacial debonding of fiber-reinforced polymer composite materials. In the preparation process of fiber-reinforced polymer composite materials, an aggregation-induced luminescence molecular coating with mechanical fluorescence response characteristics and good film-forming properties is added into the method. When the interfacial debonding occurs, the composite will emit fluorescence under ultraviolet radiation; the fluorescence images of the composite in different states are obtained, and the intensity of the fluorescence signal is quantitatively described by calculating the gray value of the fluorescence image. ; Compare the fluorescence image and gray value of the fiber reinforced polymer composite material when the interface is well bonded and the fluorescence image and gray value when the interface is debonded, so as to determine whether the composite material has interface debonding defects. The method of the invention can quickly, accurately and visually detect whether there is debonding damage in the fiber reinforced polymer composite material, as well as the location and degree of the damage, and has wide application prospects in the field of monitoring the debonding damage of the fiber reinforced polymer composite material . |
