Graphene 101: Forms, properties and applications

Graphene-enhanced composites find new applications across end markets as the supply chain continues to mature. 


Vitrimers: The reprocessable thermoset

Vitrimers are not classic thermosets and they are not classic thermoplastics, but they behave like both and as such offer the best of both worlds. CW catches up with Mallinda for an explanation.


Data security in composites manufacturing

The U.S. Department of Defense is imposing new, strict rules on companies that supply composite parts and structures in a defense contract supply chain. Understanding and following those rules will not be trivial.
