Kamal-Sourour model

Modeling the vulcanization of liquid silicone rubber (LSR). Lopez et al. [28, 29] modeled the vulcanization of liquid silicone rubber using dynamic DSC tests. In order to do this, the Kissinger model [25, 26] and the Kamal-Sourour model were used to determine kinetic parameters that fit the experimental data. The idea is to generate a single set of parameters that accurately models the used scanning rates of 1,2.5, 5, and 10 K/min. 

The model used for fitting the data was the autocatalytic Kamal-Sourour model [13, 14],... 

In order to find a unique set of parameters for all rates, Lopez et al. proposed that the activation energy E is determined through Kissinger s model, which is implemented to mathematically determine the other five parameters for the Kamal-Sourour model. The activation energy, E2, is fitted as a constant, while the four remaining parameters,... 

Figure 8.32 Comparison between measured (DSC) and computed (Kamal-Sourour) model of the heat generation during cure for two heating rates [1].

The model that best represents the curing kinetics of thermosetting resins such as epoxy and unsaturated polyester, and as reflected in a TTT-diagram, is a diffusion modified Kamal-Sourour reaction model [9, 14, 13]. To model autocatalytic cure kinetics, the model can be applied as... 

The kinetic model proposed in this report was originally based upon the kinetic model and rate expression (Equation 4) proposed by Sourour and Kamal (7). 

Before presenting the chemorheology of specific thermosets, let us first consider the factors that affect the cure kinetics of thermosets in general. For this, we consider the following empirical model of cure kinetics (Kamal and Sourour 1973) ...
