Steel / polymer / steel sandwich structures

Sandwich structures can be a solution for providing lightness and rigidity, and open up immense possibilities for many markets (automotive, electric cars, transport, naval, truck trailers, building, construction, household appliances, industry, etc.). The lighter the steel cladding, the greater the weight reduction. In terms of overall material rigidity, the polymer, whatever its nature and level of rigidity, plays a minimal role, even if it is strongly reinforced with fillers or fibers.

The world of sandwich structures can open up in many different ways.
