Abstract:
A roll having a hard roll core and an elastic covering layer on the outside of said core, said elastic covering layer comprising:a plurality of fiber layers lying radially on top of one another; and a soft matrix material with fibers embedded therein; wherein fibers of each said fiber layer extend at an angle to a longitudinal axis of said roll core and essentially parallel to one another, wherein said plurality of fiber layers includes at least two cross-composite layers, each cross-composite layer formed by at least two fiber layers lying on top of one another in which fibers of one of said at least two fiber layers are oriented in an identical but opposite manner to fibers of an adjacent layer of said one of said at least two fiber layers, and wherein said plurality of fiber layers also includes a damping fiber layer with fibers of a uniform angular position located between said at least two cross-composite layers, and an angular position of the damping fibers is substantially flatter, with respect to a longitudinal axis, than angular positions of the fibers of the cross-composite layers.
