Summary:

Dielectric composites are analyzed in terms of direct damage from shock waves, damage from longer duration slower pressures from vaporization of dielectric or metallic solids, direct magnetic forces and burning from long duration low current continuing components. Studies have included piezo blast gage pressure measurements and Schleiren photography of the shock waves in the laboratory and pressure measurements of triggered natural lightning discharges. Theoretical and experimental analysis of probable maximum shock pressures, magnetic forces and slower pressures indicate that the principal problem is introduced through long arcs developed inside sections and that the best general solution for providing lightning protection is still to keep the lightning discharge currents on the aircraft exterior or provide conductors with sufficient cross sectional area to carry the current where the currents must penetrate the aircraft
