Toray becomes Joby prepreg carbon-fibre supplier
Joby Aviation and Toray Advanced Composites finalised a long-term agreement for prepreg carbon-fibre material systems used in Joby aircraft structures.
Why it matters
The agreement provides direct evidence linking Toray’s advanced composites to a named electric-aircraft production programme.

Evidence notes
- Joby cited the materials’ specific strength and toughness as enabling structural performance at low mass.
- Toray supplies qualified aerospace thermoset and thermoplastic composite systems rather than designing the aircraft.
- The agreement placed Toray inside Joby’s continuing aircraft manufacturing supply chain.
Company context
Electric aircraft and air-taxi company with piloted commercial and autonomous defence programmes.
