Figure 3: Process monitoring of composites using smart fabric, rheological and DSC methods.

The three methods were respectively used for monitoring resistance change (a,b), viscosity (c,d) and heat flow (e,f) of two series of samples under various curing temperatures (a,c,e) and MEKP concentrations (b,d,f). Inset plots of (c) and (d) compares the rheometer determined gel time and the smart fabric sensor measured resistance change at the same gel time; Inset plots of (e) and (f) compares the DSC determined degree of cure and the smart fabric sensor measured decay of resistance change as a function of time.
