The construction of aircraft, missiles and helicopters with unprotected advanced composite materials increases their electromagnetic environment vulnerability. This is further aggravated by the diminishing susceptibility of high density digital devices (LSI, VLSI, and VHSIC) which are being utilized in the digital control systems. This study quantifies the threat to different devices in different composite airframes. It shows which composite materials exhibit the least vulnerability and initiates trade-offs to compensate it. Thin metal coatings are shown to significantly improve this with very small weight penalties for aluminum coatings. The use of coatings offers other desirable spin-offs, one being simple design composite structural joints exhibiting low electromagnetic vulnerability. (Author)
