Calorimetry differential scanning, epoxy curing

Barton, J. M. The Application of Differential Scanning Calorimetry (DSC) to the Study of Epoxy Resins Curing Reactions. Vol. 72, pp. 111 — 154. 

In this Sect, we describe the starting material impurities and their effect on the processing and cure reactions of TGDDM-DDS epoxies. The cure reactions are characterized by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) studies. The BF3 amine catalysts used to accelerate the cure of TGDDM-DDS epoxies are characterized by nuclear magnetic resonance (NMR) spectroscopy studies.

The complex sorption behavior of the water in amine-epoxy thermosets is discussed and related to depression of the mechanical properties. The hypothesized sorption modes and the corresponding mechanisms of plasticization are discussed on the basis of experimental vapor and liquid sorption tests, differential scanning calorimetry (DSC), thermomechanical analysis (TMA) and dynamic mechanical analysis. In particular, two different types of epoxy materials have been chosen low-performance systems of diglycidyl ether of bisphenol-A (DGEBA) cured with linear amines, and high-performance formulations based on aromatic amine-cured tetraglycidyldiamino diphenylmethane (TGDDM) which are commonly used as matrices for carbon fiber composites.

A study has been undertaken to attempt to determine a possible mechanism for the crosslinking of an epoxy resin with phthalic anhydride using an imidazole derivative as the catalyst. In this study we have used differential scanning calorimetry (DSC) to measure the heat of reaction and time of curing process. 

Analysis of an Epoxy Curing Reaction by Differential Scanning Calorimetry... 

The curing behavior of an epoxy system was investigated by dynamic differential scanning calorimetry (DSC). The epoxy resin (R) was a blend of bisphenol-A-diglycidylether (90%) and a monoepoxide (10%). The hardener (H) was a triethylene-tetramine-phenol-formaldehyde adduct containing 2% free phenol. 

Cure Rate Studies. The literature on curing of epoxies indicated two ways to quantitatively assess the difference in cure rate of various curing agents. Fava has reported on cure mechanism studies using differential scanning calorimetry and Dannenberg of Shell has reported on epoxy-cure mechanism studies by near infrared spectroscopy3 (NIR).
