Overview
EN 4408-003:2005 - part of the CEN/AECMA Aerospace series - defines rules for representing parts that include core materials (sandwich constructions) in technical drawings. It applies to aerospace structures using core materials such as honeycomb (alveolar materials) and foam, and is intended to be used together with EN 4408-001 (general rules for composite parts).
This standard specifies graphic conventions, identification methods, cross‑sectional representations, lay‑up diagram rules and recommended symbols to ensure clear, unambiguous documentation of composite sandwich parts.
Key topics and requirements
- Scope and application: Representation rules for parts including core materials in aerospace technical drawings; complements EN 4408-001 and EN 4408-002.
- Terms and definitions: Clarifies key concepts such as alveolar material (honeycomb), cell, tape, L and W directions, drained and perforated alveolar material, foam and sandwich (core material structure).
- Identification of core layers: Each honeycomb or foam layer must be identified; example uses a 3‑figure numbering scheme starting at 011 for core layers.
- Graphic representation:
- Alveolar (honeycomb) cores shown by perpendicular lines in cross section.
- Foam cores shown by circles in cross section.
- Areas limited by fine interrupted lines on views projected perpendicular to the sandwich plane.
- Drained and perforated cores:
- Draining notches shown by parallel lines crossing cell sides; special symbols for drained sides.
- Perforations shown by circles crossing cell sides; symbols indicate perforated sides.
- Filling zones and inserts:
- Filling zones delimited by fine continuous lines and hatched for filled cells.
- Inserts are located in filled areas; indicated by reference to cross section showing insert geometry.
- Lay‑up diagram rules:
- Each constituting element (core layer, skin, insert, filling) occupies one line in the lay‑up diagram.
- Recommended symbols and dimensional guidance (e.g., line width 0.5 mm for A4/A3/A2; 0.7 mm for A1/A0) are provided to standardize diagrams.
Practical applications
- Producing engineering drawings and CAD documentation for aircraft and spacecraft sandwich panels.
- Communicating core type, orientation (tape L/W directions), drainage/perforation details, fillings and inserts between design, manufacturing, supply chain and quality teams.
- Ensuring consistent interpretation of composites drawings for inspection, manufacturing and certification.
Who uses this standard
- Aerospace structural designers and engineers
- Drafting and CAD technicians creating composite part drawings
- Suppliers and manufacturers of honeycomb and foam core materials
- Quality assurance, manufacturing and certification teams
