With the widespread application of composite materials in aircraft structure

new demands on the lightning- strike-protection for aviation composite parts have been raised. Meanwhile

represented by VARI process

the liquid composite molding technology has caused more and more research attention. But the commonly used flow mesh will cause material waste and quality problems. Combined with the two demands above

this article introduced the lightning-strikeprotection copper mesh as flow media in the VARI manufacture process for aircraft composite parts in the surface application. We integrated the resin flow guide and lightning-strike-protection functions of copper mesh and investigated its influence on the resin flow

the relationship between the copper mesh layers and the resin permeability and the surface quality of the cured composite parts. Our research has positive significance for enriching the technical means of VARI process

improving the economical efficiency and the development of the application of VARI technology in aircraft structure.
