Jun 15, 2024 · A Time-Temperature-Transformation (TTT) diagram is created for the curing reaction of a DGEBA-based epoxy resin. It results from a kinetic analysis performed by means …

Jun 9, 2014 · Have you ever had a question about how to measure a physical property of a thermoset? Confused about what is gelation or how does vitrification impact thermoset curing …

Under the influence of temperature for thermally activated curing systems the hardener initiates ring opening of the epoxy group. A crosslinking reaction follows, during which the epoxy and …

Here we investigate the curing process of a commercial carbon-fiber epoxy prepreg using an Encapsulated Sample Rheometer and a Differential Scanning Calorimeter (DSC). The …

Aug 1, 2019 · A simple and robust strategy to generate time-temperature-transformation (TTT) diagrams for dual-curable thermosets is presented. TTT diagram is built for a dual-curable …

Aug 1, 2019 · The Time-Temperature-Transformation (TTT) diagram of a commercially available carbon fiber epoxy prepreg system has been developed by determining the gelation and …

Sep 19, 2016 · If the epoxy-amine system is exposed to temperatures higher than approximately 110 o C during use, additional curing can occur and the properties would change. If you look …

T g of epoxy resin increases as the curing temperature increases, and it is usually used between 100 and 150 °C. Figure 1a illustrates the TTT (Time-Temperature-Transformation) cure plot.

The TTT diagram aims to provide elaborate phase transition information for all cure temperatures. There have been a large number of TTT diagrams developed for numerous polymers [3].

Curing reactions of the epoxy system consisting of a diglycidyl ether of bisphenol A (BADGE n=0) and m-xylylenediamine (m-XDA) were studied to calculate time-temperature-transformation …
