In my January 2019 column, I discussed methods to determine whether properties obtained from mechanical testing of composites are correct — or even reasonable. One of the methods focused on comparing ...
This schematic shows an engineered material with composite layers. Layers of carbon fibers (the long silver tubes) have microscopic forests of carbon nanotubes between them (the array of tiny brown ...
The newly invented fiber composite could stretch the lifetime of these structures from decades to centuries.
