Overview

EN 4408-001:2005 - part of the CEN aerospace series - specifies general rules for representing parts made of composite materials in technical drawings. It applies to aerospace structures and related applications when this standard is invoked. The document complements ISO drawing standards to ensure consistent, unambiguous depiction of composite parts for design, manufacture and inspection.

Key topics and technical requirements

  • Drawing presentation: Composite-part drawings must comply with ISO 128, ISO 129-1, ISO 3098-2, ISO 5455 and ISO 5456 projection rules, with additional specific rules provided by EN 4408 series.
  • Title block and notes: Title block layout follows ISO 7200. Notes should be concise, standardized and preferably placed above the title block to preserve readability.
  • Dimensioning principle: Parts are defined as unassembled and measured at ambient conditions (20 ± 0.5 °C, 50 ± 10 % RH). Rules for deformable parts follow ISO 10579.
  • Thickness rules:
    • Structural areas: thickness is not shown directly - it results from the lay-up (number and type of layers) and is documented in the lay-up diagram.
    • Non-structural/special areas: local thickness (e.g., crimping zones) may be dimensioned and specified by note.
  • Lay-up diagram: Mandatory summary of layer structure area-by-area, including:
    • identification of laminate areas,
    • materials (fabrics, cores, adhesives),
    • ply directions and symbols,
    • theoretical ply thickness. Directions other than 0°, ±45°, 90° are indicated in the direction column or by special identification.
  • Direction key: A directional reference linked to the part view defines fibre and fabric orientations (0° chosen by the designer; + direction aligns with the direct axis system).
  • Material and area identification: Laminate areas are labelled (letter + number) and materials are specified in the lay-up diagram or notes.
  • Tolerancing & marking: General tolerances per ISO 406 and ISO 1101. Marking recommendations (ink/paint) and company-specific serialisation/manufacturing conditions are addressed.

Applications and users

EN 4408-001 is intended for:

  • Aerospace designers and structural engineers creating technical drawings for composite components.
  • CAD drafters, manufacturing engineers and production planners who translate lay-ups into manufacturing instructions.
  • Quality, inspection and procurement teams that require standardized documentation for acceptance and traceability. Use cases include wing skins, fuselage panels, sandwich structures and any composite parts where clear definition of laminate areas, ply orientation and material identification is critical.

Related standards

  • EN 4408 series: Part 2 (laminated parts), Part 3 (parts with core materials), Part 4 (winding), Part 5 (seams), Part 6 (preforms).
  • ISO references cited: ISO 128, ISO 129-1, ISO 406, ISO 1101, ISO 3098-2, ISO 5455, ISO 5456, ISO 7200, ISO 10579.
