Determination of cure mechanism inside die for a part manufacturing during large?scale pultrusion

The cure kinetics of resin, heat capacity, and thermal conductivity reinforcing materials uncured mass dictate the ultimate curing reinforced thermosets manufactured component. In this study, degree conversion from capacity by “Lumry Eyring Model” order reaction multi-regression technique using “Borchardt Daniels are calculated in finding () resin. Experimental results differential scanning calorimetry, thermogravimetry (TGA), rheological measurements were used to determine conductivity, parameters resin through several model fitting. composite ration (length vs. contact area) resistivity extracted TGA data was fitted into a specific mathematical model, which predicts behavior heated prepreg during pultrusion operation. These separate partial equation-based equation predict change temperature along axial distance radial thickness. influence operating conditions, such as rate heating (early late heating) fiber volume fraction while inside die validated with experimental results. This study evaluates extent transfer scale up steady state process. It is observed that paradigm influencing like pulling speed, thickness heater engagement on flow wall core (i.e., part being pulled) follows captured experimentally.
