Claim:
1. A method comprising: providing a first portion of a part; providing a second portion of the part, and wherein at least one of the first portion or the second portion has at least a first cavity; providing a frictional damping insert constructed and arranged to provide frictional damping of the part, the insert having thereon a coating comprising at least one of particles or fibers; positioning the insert so that at least a portion of the insert is received in the first cavity, and wherein frictional contact surfaces are provided by at least one of the first portion of the part or the second portion of the part and at least one of the insert, the coating on the insert, or the particles or the fibers, the frictional contact surfaces being constructed and arranged so that at least a portion of the frictional contact surfaces move against each other in frictional contact during vibration of the part so that the frictional contact damps vibration of the part; and joining the first portion and the second portion of the part to enclose the insert, wherein the insert and at least one of the first portion or second portion are in frictional contact so that the insert moves relative to at least one of the first portion or second portion of the part to provide the frictional damping.
