Toray TC380 New
- Chemical Family
- Epoxy & Epoxy Derivatives
Toray TC380 sets a new benchmark for toughened epoxy prepreg systems. TC380 is extremely tough with an excellent balance of OHC, OHT, CAI, and GIC/GIIC properties. It features low moisture absorption with outstanding hot/wet mechanical properties to 121°C (250°F). TC380 is optimized for out-of-autoclave/vacuum bag only (OOA/VBO) cures, facilitating construction of large or complex composite parts and assemblies. Unlike some other highly toughened systems, there is no need to sequence the prepreg front and back face, assuring robustness and simplifying lay-up. TC380 out life are 21 and 28 days, respectively. 180°C (356°F) Cure, Toughened Epoxy Resin System
