Armor plating has been used primarily in static and surface-based (land and water) equipment. Aircraft usage has been restricted due to weight restrictions. This paper takes a look at the basic theory and parameters to derive those applicable to light weight armor for aircraft. The creation of new surfaces by internal fracture removes much of the impact energy during the transient stages. Hence, the continuum formula for composites requires modification to account for transients in moduli and area variations, as also for texture variations in various layers. Equations describing variation of various material parameters are examined to give insights into ways of strengthening the composite structure.
