Abstract:Carbon fiber reinforced polymer (CFRP) composite materials are widely used. However, comparing with metals and alloys, due to the lower electrical conductivity, CFRP are prone to being damaged when subjected to lightning strikes. In this study, the current dispersion and damage characteristics of CFRP laminates under the separate injection of lightning current components A and C are compared through the morphology inspection, the ultrasonic C-scan, the residual compressive strength test, and the coupled electric-thermal simulation. It is found that under the current component A, the surface layer of the CFRP laminate produces a fiber burst zone with a length of roughly 120mm and a width of roughly 30mm, whose direction is consistent with that of the laminate. In contrast, after the application of current component C, a circular ablation pit with a diameter of roughly 60mm is produced. Comparing with the undamaged laminate object, the elastic modulus of the laminate after the injection of current component A is scarcely changed, whereas that of the laminate after the injection of current component C is reduced. The maximum compressive strengths of the laminate are slightly increased after the injection of the two components. In the coupled electrical-thermal simulation, the temperature field distribution of the CFRP laminate during the delivery of the component A has obvious directionality, which is consistent with the direction of each layer. The temperature field distribution of each layer of CFRP laminate remains unchanged during the delivery of component C, but it does not relate with the direction of each layer. The temperature field distribution of CFRP under the injection of the two components is, more or less, consistent with the experimental morphology. Obtained results in this paper reveals the damage mechanism of CFRP laminates by two lightning current components with distinctive characteristics, and can provide a basis for lightning protection of CFRP laminates.
