Abstract
A friction film for increasing friction between two workpieces includes a deformable carrier material having a porous structure and friction-increasing particles on at least one side of the carrier material. The carrier material may be a polyethylene film or a liquifiable adhesive, and the friction-increasing particles may be titanium boride particles and/or diamond particles.
Claims15
A friction film configured to increase friction between two workpieces when compressed between the two workpieces,
- wherein the friction film includes a deformable foamed polymer film having a porosity of 50% to 95% as a carrier material and friction-increasing particles on at least one side of the friction film,
- wherein zinc particles are provided on the carrier material, and
- wherein particles of a first set of the zinc particles maintain a separation between pairs of the friction-increasing particles.
A system comprising
- a first workpiece;
- a second workpiece;
- and
- a friction film between the first workpiece and the second workpiece,
- wherein the friction film includes a deformable carrier material having a porous structure and friction-increasing particles on at least one side,
- wherein in addition to the friction-increasing particles, zinc particles are applied to the carrier material as spacer particles,
- wherein particles of a first set of the zinc particles maintain a separation between pairs of the friction-increasing particles, and
- wherein the first workpiece is connected to the second workpiece in a manner that presses the friction-increasing particles into a surface of the first workpiece and into a surface of the second workpiece.
