While laser-induced breakdown spectroscopy (LIBS) has been in use for decades, only within the last two years has technology progressed to the point of enabling true handheld, self-contained instruments. Several instruments are now commercially avail

Dielectric Analysis is routinely used for monitoring the cure of thermosetting resins. Implantable, disposable sensors allow measurements of the curing process to be made in various locations throughout a part. Permanent, reusable sensors flush mount

Curing characteristics of thick composite parts have long been known to be a function of thickness and location within the parts. While cure state as a function of thickness has often been modeled, actual experimental verification has been difficult.

Recent work has shown that moisture diffusion coefficients can be measured in thin polymer films through monitoring changes in permittivity with microdielectric sensors. The sensor is constructed in silicon and consists of an interdigitated electrode

With the relatively recent trend toward adaptive process control during processing of structural composites, there is need for an understanding of the nature of variations during cure that are encountered. Part-to-part variations can arise because of
