Next-generation composites may monitor their own structural health

Carbon fiber composites—lightweight and strong—are great structural materials for automobiles, aircraft and other transportation vehicles. They consist of a polymer matrix, such as epoxy, into which reinforcing carbon ...

Reliably simulating polyurethane foams

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 ...

Weak hydrogen bonds key to strong, tough infrastructure

The right mix of hydrogen bonds in polymer and cement composites is critical to making strong, tough and ductile infrastructure material, according to Rice University scientists who want to mimic the mechanics of mother-of-pearl ...

Decreasing the mass of aircraft with polymer composites

Members of the Department of Chemistry of Lomonosov Moscow State University have created unique polymer matrices for polymer composites based on novel phthalonitrile monomers. The materials are stronger than metals, which ...
