The introduction of fiber reinforcing into the exterior finish component of an exterior wall assembly may aid in preventing catastrophic failure of the integrity of the wall during events in which high-velocity impact is likely. The most important events to address are those conditions caused by naturally occurring high winds and blast events. During these events, it has been observed that a wide range of objects become lethal projectiles that pose significant hazards to both personal injury and property damage. While layered polymer composites have demonstrated an increasing level of resistance to projectile impact, significant difficulties remain that require further research. In particular, delamination from low and high velocity impact has been a major problem that threatens the structural integrity of the panel. The use of composites for exterior sheathing is a growing area for research and architectural and civil applications in the US, and especially in Europe and Japan. For the advancement of the use of large-scale composite panels for exterior sheathing, further research regarding resistance to impact should be undertaken.
