Chemical shrinkage characterization techniques for thermoset resins and associated composites
TL;DR: In this paper, all the techniques used in the literature for the characterization of Sh of resin and composite are reported briefly with their respective advantages, disadvantage and important results, which later on has been used to find tensor of Sh for the simulation of residual stresses and shape distortion of composite part, etc.

The variation in lateral and longitudinal stress gauge response within an RTM 6 epoxy resin under one-dimensional shock loading
TL;DR: In this paper, the dynamic response of a commercially important epoxy resin (RTM 6) has been studied using plate impact experiments in the impact velocity regime of 80-960 m/s.

Effect of binder powders added to carbon fiber reinforcements on the chemoreology of an epoxy resin for composites
TL;DR: In this paper, the influence of epoxy preforming binder on the curing kinetics and chemorheological behavior of a cross-linking epoxy matrix was studied and the results proved that the addition of the binder led to a significant change of the curing behavior suggesting that the epoxy binder was an essential component needed to complete the stoichiometry of the resin-hardener mixture.

Investigation of the effect of double-walled carbon nanotubes on the curing reaction kinetics and shear flow of an epoxy resin
TL;DR: In this article, the effect of combined temperature-concentration and shear rate conditions on the rheology of double-walled carbon nanotubes (DWCNTs)/RTM6-Epoxy suspension was investigated to determine the optimum processing conditions.
