Reliably simulating polyurethane foams
Phys.org » Polyurethane
by
1y ago
Car seats, mattresses and insulation materials are often made of polyurethane foams. The foaming process of the liquid polymer emulsions is complex. Fraunhofer researchers are now able to simulate the foaming behavior and reliably characterize the material. This also works with composite materials in which the plastic foams are combined with textile structures ..read more
