Patent number: 6426124Abstract: A processed fiber is used to distribute energy from an electromagnetic (EM) energy source to a material in which the fiber is embedded. The electromagnetic energy source supplies electromagnetic energy to the fiber and the fibers emit portions of the EM energy along the length of the fiber. The sealant material absorbs a quantity of the electromagnetic energy sufficient to cure the sealant material and propagates excess electromagnetic energy through the sealant material without significant additional absorption. This prevents the sealant material from over-curing. Additionally, a fully cured material can be used to generate thermal energy and thereby serve as a heat blanket that can be used to de-ice aircraft.Type: GrantFiled: February 22, 2001Date of Patent: July 30, 2002Assignee: Sikorsky Aircraft CorporationInventors: Elliot F.
