The curing kinetics and viscosity of an epoxy resin system, SI-ZG-5A, have been characterized for application in the vacuum assisted resin transfer molding (VARTM) process. Impregnation of a typical carbon fiber perform provided the test bed for the characterization. Process simulations were carried out using the process model, COMPRO [8], to examine heat transfer and curing kinetics for a full...

Investigating the curing kinetics of a fiber prepreg system is beneficial to controlling laminate process. In present work, dicyandiamide (DICY)-cured carbon fiber/epoxy was investigated by non-isothermal differential scanning calorimetry (DSC) at 2, 5, 10, and 20°C/min attain glass transition temperature for uncured fully cured sample, which were estimated be 7.6°C 106.2°C, respectively. The a...
