Thermal Analysis of Montmorillonite/Graphene Double-Layer Coating as a Potential Lightning Strike Protective Layer for Cross-Linked Epoxy by Molecular Dynamics Simulation
Source abstract
Abstract
Nonreactive molecular dynamics simulations were performed to determine the thermal conductivities and through-thickness temperature profiles of unprotected cross-linked epoxy, as well as protected epoxy with graphene (Gr) and montmorillonite (MMT)/Gr surface coatings against lightning strike damage. Three representative hot surface temperatures of 500, 1000, and 10000 K were used for thermal analysis. The MMT/Gr double-layer coating provided the most efficient thermal shielding of the epoxy sublayer, and the epoxy/MMT/Gr system exhibited a 55% lower thermal conductivity than the neat epoxy. The results imply that the MMT/Gr double-layer coating may be used for lightning strike protection.
