Feature Article Figure 6. Estimation of heat transition from the thermoplastic to the pultruded thermoset profile. Results: Process Development In order to overcome the challenges, a sound adjustment of the development of the viscosity of the thermoset matrix system is performed. The effect of different temperature levels and possible material degradation is estimated a-priori by an analytical calculation earlier. The resulting process technology was discussed already. The process is designed to work at 1.0 m/min due to machine restrictions. The most important part of the process, the die technology, has been pointed out. The process has been put into operation to give a proof of concept. Temperature and Viscosity Development for the Thermoset Pultrusion An analytical calculation has been conducted to estimate the heat transition from the hot thermoplastic top layer (assumed: constantly 230°C, infinite heat transfer coefficient) to the cooler pultruded composite profile. The temperature of the composite profile is assumed to SAMPE Thanks Our Corporate Partners 1519 Eastgate Drive Westmoreland Mech.
