SoftGrip blind rivet nuts from GESIPA make it easy to produce high-quality threads in sensitive lightweight applications Carbon fibre-reinforced plastics (CFRP) offer indisputable and fascinated advantages when it comes to saving weight. They are, however, particularly demanding when selecting the partner material. Standard joining elements simply will not do for this high-grade material. GESIPA has now developed a blind rivet nut for composite materials that meets the demanding requirements. The SoftGrip blind rivet nut from GESIPA is a further development of the tried and tested PolyGrip multi-range blind rivet nut. With the aid of a precisely controlled setting procedure, the component is barely subjected to bearing stress and contact pressure. The bulb that forms flat on the component with a large (larger than average) diameter ensures outstanding mechanical properties. Component damage such as crushing, cracking, delamination etc. are therefore effectively avoided. Thanks to the controlled formation of the bulb and the thus reduced bearing stress, minimal edge spacing of the blind rivet nut can be realised in connection with large hole tolerances. The use of high-grade stainless steel A2 materials (A4 on request) additionally makes the load bearing thread highly resistant to corrosion. Advantages
- Fast processes
- Tight fit with the components
- Process monitoring and process control are possible
- High strength
- Not dependent on surface properties
- No other materials required (adhesive)
- No ageing
- Accessible from one side
- No delamination of the CFRP
- Smaller edge spacing of the holes
- Large grip range
- Stainless steel for high corrosion resistance
- Higher hole drilling tolerances
