The 603 is a heatresistant epoxy resin. Its glass transition temperature and heat decomposition temperature are 225益and 387益respectively. The solidifying characteristics are studied by geltime,DSC and rheology,
and then its curing technique is confirmed. Draping prepregs can be made through solvent and melting. The composites
of T700/603 and T800/603 can be used as structural components with high performance.
