Aerospace-grade carbon-fibre composite prepreg
Aerospace-grade carbon-fibre prepreg supply is concentrated in Toray (Japan), Hexcel (USA/France), and Solvay (USA/Belgium). Indian industry has disclosed intent to develop indigenous prepreg production; no qualified aerospace-grade line has been announced. Underpins composite manufacture across TASL, TLMAL, and the HAL composites ecosystem.

Indian capability
None at aerospace-grade scale. Indian composites capacity exists for non-aerospace applications.
Localization potential
L2 (Indian prepreg production) in 5-7 years — capital-intensive, IP-heavy
Component: Composite prepreg (carbon fibre + resin system) · System: Airframe Structure
Affected platform: Embraer C-390 Millennium
Supplier profile: Toray Industries (Japan) + Hexcel (USA/France) + Solvay (USA/Belgium)
