Polyimide-carbon fiber composites
These are the preferred design materials for structural components found in today’s airframe and propulsion systems for aerospace vehicles
Composites are also prevalent in high-performance automotive racing, with a slow but steady technology transfer to commercial vehicle components.
Composites offer both lightweighting and thermal resistance, with service temperatures of 400°C to 500°C. Polyimide matrix resins are formulated for property as well as process considerations. Fabrication requires attention to melt processability, dictated by the selection of diamine, dianhydride and other reactive ingredients.
- Aerospace structural components
- Automotive underhood components
- Industrial bushings
Why should I choose polyimide composites?
- High Tg
- Retained structural strength at high temperatures
- Retained oxidative stability
- Dianhydrides must be matched to the corresponding diamines for optimal properties of the polyimide.
