Until now, metal replacement in vehicles has typically focused on lower-load parts, but in order to incorporate these new lightweight materials into higher-load, harsher-environment applications, manufacturers need a more reliable and rugged method of structural bonding.
With an adhesive layer that contains nitrile rubber and a phenolic resin, tesa HAF® solutions function as thermosetting adhesive tape. When heated, a chemical reaction is started that creates a securely bonded system. Once fully cured, the heat activated film adhesive does not go back to its original status when re-exposed to heat.
This also offers high chemical resistance to engine oil and solvents and a high cohesiveness at frictional heat (up to 350°C). tesa HAF® bonds very well to steel and carbon fiber, which makes it an excellent solution for bonding carbon fiber linings to synchronizer rings, but the potential of this next-generation bonding solution is not limited to a vehicle’s transmission. Other proven applications include bonding carbon fiber to clutch discs, mounting sensor plates for gear control, and brake shims to brake pads.
