Aircraft transparencies represent one of the most significant life cycle cost to the u.s. air force. the major cause for the optical impairment is the degradation in plastics known as crazing which occurs due to surface stresses and is accelerated by the environmentalfactors. the objective of the… More

The use of fibrous composites has greatly increased in the Navy. These composites have introduced challenging problem in process manufacturing of these materials. Dielectric sensors as well as ultrasonic embedded wave guides have been successful in cure monitoring; however, they have two severe… More

The proposed concept combines the advantages of fiber optic geometry and piezoelectric materials to produce a superior active strain sensor. The sensor will be produced with innovative manufacturing processes of sputtering multi-layered thin films of piezoelectric materials and insulators. Such a… More

Over a million workers in the U.S. are routinely exposed to vibration from hand-held tools.Prolonged use of these tools causes Raynaud's Disease or Vibration-induced White Finger. For a varietyof reasons, the hand-held tools did not get the benefit of technological advances. This project willconduct… More
