Overview

SIST EN 2243-3:2006 is a European standard under the Aerospace series developed by the European Committee for Standardization (CEN). It specifies the test method for determining the peeling strength of structural adhesives used in metal-to-honeycomb core assemblies. This test method, focused on peeling tests at ambient or other specified temperatures, is essential for evaluating the bonding performance of non-metallic aerospace materials, particularly structural adhesives in critical aerospace components.

This standard ensures consistent, reliable assessment of adhesive strength in aerospace manufacturing and maintenance, thereby contributing to safety, quality assurance, and regulatory compliance.

Key Topics

• Scope: Defines testing requirements for peeling strength of structural adhesive joints between metal skins and aluminium honeycomb cores.
• Materials: Aluminium alloy EN 2090 for skin, aluminium honeycomb core per EN 4606, and adhesives prepared following specified surface treatments (EN 2334).
• Testing Apparatus: Uses a peeling jig with a drum of 50 mm radius, load clamps, and a tensile testing machine compliant with EN ISO 7500-1.
• Test Procedure:
  • Cutting panels into test pieces with precise dimensions.
  • Conditioning at specified humidity and temperature.
  • Fixing test pieces on the peeling jig and loading at 25 mm/min.
  • Testing at ambient (23 ± 2 °C) or controlled temperatures with temperature stabilization.
• Measurement & Results:
  • Measurement of peeling load (F), rolling load (F0), and peeling strength (τ) calculated through averaged load over specific peeling length.
  • Continuous displacement and load are recorded to produce peeling diagrams.
• Test Reporting: Comprehensive documentation including adhesive and material identification, surface preparation, bonding conditions, test machine type, load-speed, environmental conditions, failure modes, statistical data, and deviations.

Applications

SIST EN 2243-3:2006 has practical application in the aerospace industry for:

• Quality Control: Verifying adhesive bond strength in metal-honeycomb composites to ensure structural integrity.
• Material Qualification: Assisting manufacturers in certifying adhesives and honeycomb materials for aerospace usage.
• Design Validation: Supporting engineers in selecting and validating adhesive systems used in lightweight aircraft structures.
• Maintenance & Inspection: Assessing aging or repaired adhesive joints to maintain airworthiness.
• Research & Development: Providing a standardized method for advancing adhesive technology and evaluating new bonding materials.

These applications contribute to safety-critical aerospace goals such as weight reduction, improved fuel efficiency, and long-term durability of aircraft components.
