General Information

Overview - EN 2564:2018 (Aerospace series)
EN 2564:2018 specifies laboratory methods for determining the fibre, resin and void contents of carbon fibre laminates used in aerospace applications. The standard describes two acid‑digestion procedures (Method A - reference method, and Method B - a simplified, higher‑throughput method), specimen preparation, required apparatus and reagents, safety precautions and how to report results. Results are reported both by mass and by volume, using measured specimen density and published fibre/resin densities.
Key topics and technical requirements
- Scope: Measurement of fibre content (mass and volume), resin content (by correlation), and void content (volume) for carbon fibre laminates intended for aerospace use.
- Two digestion methods:
- Method A: Reference procedure using a closed pear‑shaped flask, concentrated sulphuric acid and hydrogen peroxide with controlled heating and stepwise peroxide addition.
- Method B: Simplified open‑beaker method (fume cupboard), suitable for high throughput when adequate safety measures and validation are in place.
- Specimens: Minimum sample mass typically 1–5 g; at least three specimens evenly distributed and cut ≥10 mm from edges unless otherwise agreed.
- Apparatus & reagents: balance (±0.1 mg), sintered glass crucible, concentrated sulphuric acid, hydrogen peroxide (300–500 g/l), acetone, distilled water, oven (120 ±5 °C), sand bath/reflux options, protective equipment.
- Density measurements: Specimen density in accordance with ISO 1183 (method A) and fibre density per ISO 10119 or supplier data.
- Expression of results: Fibre content by mass and volume, resin content by mass and volume, void content by volume - with clear calculation procedures and an estimated absolute error for void content (~±1% due to density uncertainties).
- Health & safety: Strong emphasis on PPE, fume control, safety screen and documented risk assessment for handling corrosive oxidizing mixtures.
Practical applications and users
- Who uses EN 2564:2018:
- Aerospace materials laboratories performing quality control and incoming inspection of carbon fibre laminates.
- Manufacturers of composite parts and prepregs who must verify fibre/resin ratios and porosity.
- Research & development teams validating layups, process adjustments and comparative studies.
- Certification bodies and auditors assessing material conformity for structural aerospace components.
- Why it’s useful:
- Ensures consistent, traceable measurement of fibre/resin ratios and porosity that directly affect mechanical performance, weight and durability of aerospace composite structures.
- Provides a standardized test report format and traceability requirements (batch ID, sampling, individual and mean values, deviations).
