WebFeb 28, 2024 · When the degree of cure is low, the viscosity of thermoset resins will decrease if temperature increases, which is the same for thermoplastic materials . However, if the processing temperature reaches a certain level, the number of cross-linkings will increase rapidly. Hence, the degree of cure rises significantly, and it results in an ...
WebOct 27, 2014 · Guest Post by Dr. R. Bruce Prime This is the first post in a new series on Thermoset Cure Kinetics, where we introduce the basic principles of kinetics and their general application to thermoset cure. In the following posts we describe important applications to the characterization and design of thermoset cure processes. A … WebOne important aspect of a thermosetting resin, such as an epoxy, is the cure kinetics associated with the material. Kinetics refers to the modeling of the effects of temperature and time on the degree of cure of a thermosetting resin. The estab-lishment of cure kinetics provides the scientist or process control engineer with
WebOct 17, 2016 · In the last post we started our discussion of how to monitor thermoset curing during processing and showed that the glass transition temperature (Tg) is a potential physical property that is useful for cure monitoring. A common and easy way to measure Tg is using differential scanning calorimetry (DSC), but there are other … WebNov 4, 2024 · This technique eliminates the high-temperature curing process that often involved during thermal cure. Thermosetting photopolymers claim almost half of all 3D printing materials and have been widely applied in various fields owing to good compatibility with high-resolution 3D printing technologies .
