65% Weight reduction through LOCTITE Composite matrix resin
In collaboration with Benteler SGL, Henkel was asked to develop an advanced Composite matrix resin based on polyurethanes to produce the first composite leaf spring manufactured in RTM process for high-speed, mass production.
A resin based on polyurethanes opens new application opportunities in contrast to existing epoxy resins, including fast injection, very low viscosity and low-cure exothermic, as well as excellent toughness.
Henkel developed a polyurethane-based composite matrix resin which fulfilled the performance criteria of the matrix in terms of physical properties, processability as well as static and dynamic behavior in a composite part.
Our LOCTITE MAX 2 composite matrix resin enables:
- Superior fatigue resistance under dynamic loads
- Suitable for high-speed RTM because of short cycle times
- Controllable, safe and fast processing
A composite leaf spring offers OEMs an alternative that:
