Woven carbon/epoxy laminate
Woven carbon/epoxy laminate is a system-level composite reference. Its properties depend on reinforcement, matrix, fibre volume, lay-up, cure and test direction.

| Density | 1.45–1.60 | g/cm³ | Representative generic grade; verify supplier, condition and test method |
| Longitudinal or principal modulus | 50–80 | GPa | Representative generic grade; verify supplier, condition and test method |
| Longitudinal or principal tensile strength | 600–1000 | MPa | Representative generic grade; verify supplier, condition and test method |
| Indicative service temperature | 90–130 | °C | Representative generic grade; verify supplier, condition and test method |
| Transverse/shear response | Architecture dependent | — | Representative generic grade; verify supplier, condition and test method |
| Damage tolerance | System and lay-up dependent | — | Representative generic grade; verify supplier, condition and test method |
Conditions
Cured, dry reference
Representative cured laminate.
Hot/wet conditioned
Environmental condition; exact moisture uptake and temperature required.
03
Processing and use
Processing
- Fibre orientation, volume fraction, void content, cure state and defects must be recorded with every property dataset.
- Laminate properties cannot be inferred from fibre and resin properties alone.
Applications
- Lightweight panels and shells
- Primary or secondary structures
- Energy-absorbing or corrosion-resistant components
Selection considerations
- Treat this as a material-system reference, not a universal laminate allowables set.
- Check open-hole, compression-after-impact, environmental and joint behaviour for structural use.

Confirm the applicable specification, product form and condition before using values for design or procurement.
Supply and sustainability
Available as prepreg, dry reinforcement, moulding compound or consolidated panel depending on system.
Long service life and mass reduction can be valuable, while separation and recycling remain system dependent.
Strategic context
Enables high specific stiffness, tailored anisotropy and multi-functional structures.
