SAMPE 2013 Long Beach new product showcase
The SAMPE 2013 trade show (May 6-9, in Long Beach, Calif.) was the venue for introductions of a large number of new composite materials, technologies and manufacturing processes. Here's the HPC editorial staff's compilation of what was on display.

SMPs: Reshaping old realities
Moving quickly from science fiction to science fact, shape-memory polymer composites show great potential in aerospace applications.

Shape shifters: The molecular basics
The key to SMP shape change is the fact that an SMP can exhibit a radical transformation from a rigid polymer to a malleable elastomer and back again.
