Coatings for Lighting Protection of Structural Reinforced Plastics. Part 1
Abstract
Coatings and coating systems were developed for protection of boron and graphite fiber reinforced plastic composites from structural damage by lightning strikes. The effectiveness of the protective capability of the proposed coating systems was tested with an artificial lightning stroke consisting of both high current and high coulomb components. The primary criterion of successful coating was the capability of a test panel to sustain a simulated lightning discharge without structural damage to the composite substrate. Numerous coatings or coating systems have been developed and evaluated. They can be classified into the following general categories: continuous metal foils; woven metal wire fabrics; knitted metal wire mesh; plasma and flame sprayed aluminum; metal pigmented paints; and nonmetallic pigmented paints; and nonmetallic pigmented paints with or without undercoatings. Several coating systems show protective capability. Aluminum knitted wire mesh and aluminum woven wire fabric are considered to be the most promising coatings.
