Epoxy Curing

摘要

Various room temperature (RT)-curable epoxies used for vacuum-assisted resin transfer moulding (VARTM) of large structure manufacturing have been characterised. Six epoxy candidate resins: X-40, 780-33, 780-35, 8601/8602, 8602, 8603, and two vinyl ester resins (VE), 411-350 and 411-510A, are physically and thermo-chemically characterised. All the resins are cured at RT with extended periods of time. The degree of cure for 24h RT-cured samples ranged from 70 to 85% for epoxies and is comparable with the baseline VE systems (75%).
