Product description

TC380 is a toughened epoxy prepreg, balanced with excellent OHC, OHT, CAI, and GIC/GIIC properties.

TC380 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 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.
