WebTherefore the TTT diagram allows optimised operations and handling of an epoxy system on site allowing users the flexibility to adapt to varying environmental conditions or practical constraints. 1 INTRODUCTION Epoxy thermosets are the most widely used structural adhesive in civil engineering composite applications. WebThe data are then used to form time-temperature-transition(TTT) diagram of the system, which serves to be a tool for process optimization of epoxy-matrix composites. A new cure processing is therefore derived from the TTT diagram.
