The key issues are measurement and control [1, 2] of:

Principal sensor technologies include electrochemical – dielectric – optical fibre – IR and Raman spectroscopy – ultrasonic – mechanical impedance analysis.

Dielectric cure monitoring systems have been developed by Micromet (marketed as Episilon by the Netzsch Group), Ashland Performance Materials, formerly Signature Control Systems, (SmartTrac®) and the DYNAMIC consortium (an EU SME-2 Collective Research project), amongst others.

Process control technologies include proportional-integral-derivative, fuzzy logic and artificial neural networks.
