“…Chemical reactions that take place during the crosslinking process pull end groups together and gradually transform a liquid into a crosslinked solid. The formation of polymer networks leads to a volumetric shrinkage, which often exceeds 6% and can be as high as 10% for some resins . This cure‐induced volume shrinkage in thermosets causes warpage and residual stresses in thermoset composites.…”

This article reviews the field of molecular simulations of thermoset polymers. This class of polymers is of interest in applications ranging from structural components for aerospace to electronics packaging and predictive simulations of their response is playing an increasing role in understanding the molecular origin of their properties and complementing experiments in the search for tailored materials for specific applications. It focuses on modeling and simulation of the process of curing to predict the molecular structure of these polymers and their thermomechanical response by all-atom molecular dynamics simulations. Results from Monte Carlo and coarse-grained simulations are briefly summarized.

“…This shrinkage is due to both thermal expansion (contraction) and chemical shrinkage. For epoxies, the volumetric shrinkage can be as much as 6% [1][2][3]. For polyesters, this shrinkage can be even higher.…”

A new method for the determination of shrinkage and modulus development of thermoset resins is described. The method uses the change in the time of travel of longitudinal ultrasonic waves in a couplant to determine the change in height of a column of resin. This change in height is used to determine shrinkage. The method also uses the time of travel of ultrasonic waves through a column of resin to determine the modulus of the resin. The technique allows continuous monitoring of shrinkage and modulus as the material changes from the liquid state to the solid state. This method is used to determine the shrinkage and modulus development for a common epoxy resin.

“…Only a few dilatometers, such as those of Bell [8], Yates and McCalla [9], can be used in a reacting system. With reacting systems, especially during the adhesive cure process, a basic dilatometer is sufficient up to the gelation point since the mixture can easily flow through the capillary.…”

“…Once the mixture goes beyond the gelation point into the glassy state or semisolid, other techniques should be used to monitor the cure process. For example, Yates and McCalla [9] used two separate dilatometers, one for liquid and other for solid, to measure the epoxy resin volume change with cure. More recently, Schoch et al [10] described a method for the in situ determination of shrinkage during the cure of thermosets using dynamic mechanical analysis (DMA) instrumentation.…”
