Abstract <p>Composite materials play an increasingly significant role in light weight construction due to their high performance in tensile and flexural strength. Polymeric resins such as thermosets and thermoplastics serve as the matrix of composites, influencing its properties. Elium®150 is an amorphous thermoplastic resin to combine the tensile and flexural performance of thermosets with the recyclability of thermoplastics. To achieve the optimal performance of the resin, curing is needed to start chemical bonding reactions. The goal of this work is to simulate the released heat by Elium®150 during curing for a better curing quality. This leads to a better control of the curing to avoid critical temperatures, leading to thermal damages, as typically encountered for the curing of thick thermosets like epoxies for instance. The simulation is based on a cure kinetics analysis taking into account chemical laws such as diffusion during the reaction. The simulation is performed by the forward Euler method. The results of the simulation for the degree of conversion and the heat flow during isothermal curing match the experimental data. The simulation of non-isothermal curing cycles is coherent with literature, but does not match the experimental data. To validate the discussed reasons about the deviations between simulations and experiments, more experiments need to be conducted. The collected data can be further used to simulate curing processes of large resin parts by a finite element method.</p> Graphical abstract <p><b>It’s a match!</b> To prevent overheating of the Elium®150 thermoplastic resin, this study predicts the released heat of the resin during curing. The prediction is based on a cure kinetics analysis and conducted by the forward Euler method. The cure kinetic model is based on the Kamal &amp; Sourour model, with an additional diffusion factor implemented by Fournier </p>
