Foam including surface-modified nanoparticles

The present invention provides internally damped stators, rotors, and transformers; internally damped cores from which they may be made; and a method of making the aforementioned.

Internally damped stator, rotor, and transformer and a method of making

The present invention relates to a vibration attenuating article that has a non-tacky film covering enclosing all or a significant portion of the surface of a vibration attenuating material, wherein at least a portion of the vibration attenuating surface covered by the film covering is a three dimensional surface. A layer of adhesive must be present on at least a portion of the exterior film covering when all of the vibration attenuating material is covered by the exterior film covering.

Vibration and shock attenuating articles and method of attenuating vibrations and shocks therewith

A pressure-sensitive adhesive tape comprising a plurality of superimposed layers, at least one outer layer being a pressure-sensitive adhesive layer, contiguous layer defining an interface therebetween, each of said layers comprising a photopolymerized matrix of polymeric chains; said polymeric chains extending from the matrix of one of said layers through said interface into the matrix of a contiguous layer; said polymeric chains comprising polymerized monomers having migrated from the matrix of each contiguous layer prior to polymerization, whereby said layers cannot be delaminated.
