SIST EN 2743:2004 - Aerospace series - Fibre reinforced plastics - Standard procedures for conditioning prior to testing unaged materials

Overview

EN 2743:2001 is a European standard developed by CEN under the aerospace series, focusing on fibre reinforced plastics (FRP). This standard defines standard procedures for conditioning unaged fibre reinforced plastic materials ahead of testing. It applies to both the reinforcing fibres and cured resin systems used in aerospace applications. The conditioning process ensures that specimens are prepared consistently in the as-cured state to maintain the integrity and comparability of test results.

The document is key for manufacturers, testing laboratories, and quality assurance professionals within the aerospace industry who work with advanced composite materials. It supports the production of reliable data on material properties by controlling test sample moisture content and environmental exposure prior to testing.

Key Topics

  • Conditioning Definition: Procedures to bring materials to equilibrium at specific temperature and humidity levels before tests.
  • As-Cured Condition: The target state of materials immediately after manufacture, with moisture content not exceeding 10% of the maximum moisture absorption at 85% relative humidity.
  • Standard Atmospheres: Specifies nominal temperature and relative humidity levels such as 23°C and 50% RH for conditioning and testing.
  • Conditioning Types: Four types (A, B, C, D) defined to suit different testing requirements and environmental controls.
    • Type A is the most common, emphasizing storage in sealed containers with desiccants and testing within 168 hours.
  • Conditioning Apparatus: Includes climatic chambers, sealed containers, desiccants, and absorbent materials to maintain environmental control.
  • Procedures: Guidelines for handling, storage, drying (if required), and exposure limits during machining or handling to avoid moisture uptake.
  • Reporting Requirements: Specifications on what data must be recorded and reported, including traceability information, conditioning method, moisture absorption, and any anomalies.

Applications

EN 2743:2001 applies primarily in the aerospace sector, where fibre reinforced plastics play a crucial role in aircraft structural components due to their high strength-to-weight ratio and fatigue resistance. Typical applications include:

  • Aerospace component manufacturing: Ensuring consistent test results for quality verification of composite parts.
  • Material research and development: Providing a standard framework for conditioning test specimens to evaluate new FRP materials or resin systems.
  • Certification and compliance testing: Meeting regulatory and customer requirements for material performance under standardized pre-test conditions.
  • Failure analysis and structural integrity assessments: Accurate baseline conditions help in understanding material behavior under service conditions.

By standardizing the method of conditioning, EN 2743 helps reduce variability in composite material testing, which is essential for certification and ongoing quality control in aerospace composite manufacturing.

Related Standards

EN 2743 references and complements other aerospace and materials standards, such as:

  • EN 3615: Aerospace series - Procedures for determining exposure conditions to humid atmosphere and moisture absorption in fibre reinforced plastics. This is critical for evaluating moisture uptake and equilibrium states.
  • AECMA Prestandards: Various prestandards by the European Association of Aerospace Manufacturers that guide testing and material specifications for aerospace composites.
  • Test Methods for Preimpregnated Materials: Separate conditioning requirements apply to uncured preimpregnated materials, which are covered under different, specific technical specifications or test methods.

Using EN 2743 together with these related standards ensures comprehensive coverage of material conditioning and testing protocols, enabling consistency, traceability, and reproducibility across aerospace composite testing laboratories.
