Toray TC380 New

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

Technical Details & Test Data

Curing Method
  • Properly prepare the tool surface with release coat or film.
  • Lay-up part using standard debulking procedures.
  • Dam the edges of the part for cure.
  • Place one ply of porous Teflon® or perforated Teflon onto the bag surface of the part
  • Place bleeder layers over the porous Teflon material and trim to the part periphery.
  • Place a non-porous layer of Teflon over the part.
  • Utilize a breather cloth to assure a clear path for vacuum.
  • Install vacuum bag on the tool for cure.
  • Follow the provided Toray Advanced Composites cure cycle for the particular resin system.

Storage & Handling

Shelf Life
  • Out Life: Up to 28 days at ambient
  • Frozen Storage Life: 12 months at -18°C (< 0°F)

Out life is the maximum time allowed at ambient temperature before cure. *Ambient is 18–22°C (65–72°F)
