Metal fibers and fabrics as shielding materials for composites,missiles and airframes

摘要

The advantages of metal fibers as shielding materials areexamined, including minimal alteration of base resin properties,shrinkage similar to unfilled resins, excellent abrasion and corrosionresistance (long life), and cost effectiveness. Applications of metalfibers as related to EMI (electromagnetic interference), ESD(electrostatic discharge) and lightning-strike problems in compositestructures are examined. The characteristics of nonwoven metallicfabrics, continuous multifilament yarns, and broken fibers are examined.It is concluded that metal fibers have the ability to solveever-increasing shielding demands in an effective manner with currentprocesses. They are also easily combined with many of the newengineering resins with minimal effect on resin characteristics
