An aircraft control system component, such as a bellcrank, having sideplate members of three-ply laminates bonded together with an elastomer-modified epoxy, with the thickness of the central ply twice the thickness of the end plies, and with the outboard end ply being of selected thickness and yield strength so that when petalling occurs therein due to the passage of a projectile therethrough, the petals are deformable under control loads when they come in contact thereafter with associated parts to thereby permit the control system to continue to perform its function due to the improved ballistic tolerance of the component. |
