0.4 Advantages and limitations of adhesive bonding technology
Advantages of adhesive bonding technology
- Joining of different materials possible
- Planar load transfer and uniform stress distribution without stress peaks
- Preservation of material properties due to low thermal loads and no damage to the materials
- High freedom of design
- Integration of other functions (e. g. noise insulation, vibration damping, sealing)
- Thermal and electrical insulation
- Tolerance compensation
- In some cases increased productivity
- Prevention of contact corrosion
- …
Limitations of adhesive bonding technology
- Limited thermal loads
- For many materials and processes complex surface treatment necessary
- Specific processing and curing conditions must be observed
- In some cases long curing times
- Ageing due to weathering and/or other influences
- …
Definition of “adhesive bonding”:
The joining of substrates using an adhesive
Definition of an “adhesive” (DIN EN 923):
An adhesive is a non-metallic material which can join substrates together via adhesion (surface forces) and cohesion (inner strength).
