Study on Lightning Damage Characteristics of Carbon Fibre Composites with Metal Mesh
In the aviation field,lightning protection of carbon fiber composite materials is an important research point.In the engineering field,metal mesh is widely used for lightning protection of carbon fiber composite materials.In this paper,the lightning damage characteristics based on lightning strike test method are studied for carbon fiber composites with metal mesh.For the carbon fiber composite laminate and honeycomb sandwich structure with metal mesh,the lightning current component of combined current waveform is applied to evaluated the lightning damage suppression ability of the metal copper mesh.The research shows that the lightning strike damage region presents an obvious oval shape,and the carbon fiber composite materials only has a small amount of ablation damage of the resin matrix.The metal copper mesh can effectively protect the carbon fiber composite material from lightning strike.
