Abstract

This paper reports the fabrication and characterization of a novel silver modified buckypaper-carbon fiber/phenol-formaldehyde (SMBP-CF/PF) composite for lightning strike protection (LSP). The composite not only provides electrical protection with the SMBP, but also effectively reduces the lightning strike (LS) damage with the CF/PF layer for thermal dissipation. Residual strength rate of the SMBP-CF/PF-CFRP composite maintains 97.25% after the LS test. Compared with commercial materials, the usage of the SMBP-CF/PF composite demonstrates weight-reduced as well as the excellent LSP performance. Therefore, the lightweight SMBP-CF/PF composite can be applied as the novel LSP material for aircraft.
