Isothermal pultrusion

In this section, we will describe the application of the rheokinetic model to adiabatic and isothermal pultrusion by the RIP process. Adiabatic pultrusion is defined as a pultrusion... 

Figure 1.20 Conversion in an RVE during adiabatic (top line) and isothermal (bottom line) pultrusion of glass fiber nylon 6 composite when the initial temperature for adiabatic pultrusion and the isothermal pultrusion temperature were 136°C...

Fig. 9. Master cure curve for polyurethane pultrusion resin system. Data points from isothermal DSC and DSC simulated cure profiles were shifted to times at 80°C by means of equation 14 using the activation energy measured from multiple heating rate DSC. The solid line is calculated from the second-order kinetic equation found to fit the master...

Price (21) analyzed the thermorheological aspects of the processing of epoxy-carbon fiber and polyester-glass fiber. He used a heat transfer model for pultrusion and examined two limiting cases i) isothermal case with uniform die wall temperature and ii) adiabatic case where heat conduction was considered negligible. However no correlation between process variables and temperature profiles was discussed.
