Joint strength test
We offer:
- Experiment design
- Sampling and conditioning of metallic and composite materials
- Testing joints at room temperature
- Joint strength at cold temperature (down to -150°C)
- Joint strength at elevated temperature (up to 280°C)
- Fracture surface analysis
- Statement of conformity to specification
Equipment (selection):
