Toughening up polymer composites.

Toughening up polymer composites

Chemical engineer E. Bruce Nauman of the Rensselaer Polytechnic Institute in Troy, N.Y., has invented a chemical process for making tougher composite materials. The process, called "compositional quenching,' involves dissolving two incompatible polymers--ones that have the same kind of relationship that oil has with water--in a common solvent and then heating the mixture quickly under pressure.

The result is a new composite material that is tougher than many polymers and other composite materials now available. Such a material's greater resiliency, says Nauman, would make it useful for football helmets and automobile bodies.
