TLDR
A review of chemorheological techniques and measurement systems for thermoset resins is presented in this article, with particular emphasis on the Chemorheology techniques and measuring systems.Abstract:
A review of current chemorheological techniques and measurement systems is presented for unfilled and filled thermoset resins. The specific measurement techniques for the kinetics, chemorheology, and modeling of these systems are presented, with particular emphasis on the chemorheological techniques and measuring systems. These techniques and measurement systems provide a greater understanding of traditionally complex thermoset processes, provide effective quality control measures for these processes, and will reduce design and operating costs in associated industries.read more

Real-Time FTIR and in Situ Rheological Studies on the UV Curing Kinetics of Thiol-ene Polymers
Bor-Sen Chiou,Saad A. Khan +1 more
TL;DR: In this paper, real-time FTIR spectroscopy and in situ dynamic rheology were used to characterize the UV curing kinetics of a thiol-ene system containing trimethylolpropane tris(2-mercaptoacetate) and trimethyllpropane diallyl ether.

Viscoelastic Properties of an Epoxy Resin during Cure
TL;DR: In this article, the authors used parallel plate rheometry to measure the material behavior below the gel point of the epoxy network and converted the data to the stress relaxation modulus for comparison of the material behaviour among various cure states and between the two experimental techniques.

Kinetics and thermal characterization of thermoset cure
Musa R. Kamal,S. Sourour +1 more
TL;DR: In this paper, a new model for the kinetics of isothermal cure was proposed based on a new differential scanning calorimeter (Perkin-Elmer DSC-1) which is used to characterize the cure of a general-purpose polyester during isothermal and scanning experiments.

Can the gel point of a cross-linking polymer be detected by the G′ – G″ crossover?
TL;DR: In this article, it was shown that there is only one class of network polymers for which the gel point coincides with the crossover, and the crossover cannot be used for detecting GP.

Rheology of Suspensions in Polymeric Liquids
TL;DR: In this article, the flow behavior of concentrated suspensions is reviewed for the processing of composites and similar polymeric materials, and the state of the art is a good one: a small number of experiments on a new formulation frequently suffice for a general prediction of flow behavior when solids are suspended in viscous molten polymers and in many instances, even a priori predictions of the viscosity are possible.

Differential scanning calorimetry of epoxy cure: isothermal cure kinetics☆
S. Sourour,Musa R. Kamal +1 more
TL;DR: In this article, the authors used a differential scanning calorimeter (DSC) under isothermal conditions in the range 50-150°C to collect and process rate and integral heat of reaction data during cure.

Multiphase flow in polymer processing
TL;DR: Two types of multiphase flow may be distinguished on the basis of their degree of phase separation as mentioned in this paper, where one or more components exist as discrete phase, dispersed in another component forming the continuous phase.
