Overview

EN 6035:2015 (Aerospace series - Fibre reinforced plastics - Test method - Determination of notched and unnotched tensile strength) is a European standard developed by CEN for determining the tensile strength properties of fibre reinforced plastic composites. This method is specifically designed for aerospace applications where consistent mechanical performance is critical. The standard applies to composite laminates reinforced with either unidirectional plies or woven fabrics and provides guidance on preparing, conditioning, and testing specimens to measure both notched and unnotched tensile strength.

By following EN 6035:2015, organizations can assess the mechanical integrity and durability of advanced composite materials, supporting quality control and material selection in aerospace engineering.

Key Topics

• Test Methodology: The standard outlines procedures for conducting tensile tests on both notched (with an intentional cut or notch) and unnotched specimens to evaluate the mechanical response of fibre reinforced plastics under load.
• Specimen Preparation: Guidance is given for the precise preparation of test specimens, including dimensions, configuration, and tabbing when necessary. This ensures reliable and repeatable results.
• Conditioning and Ageing: Procedures for conditioning specimens, including ambient and controlled environments, as well as post-exposure to humidity or chemical fluids, are specified to reflect service conditions.
• Measurement Requirements: Detailed measurement techniques for specimen thickness, width, and alignment during testing. Accuracy and calibration of instruments are emphasized.
• Test Reporting: The standard mandates comprehensive test reporting, including material identification, specimen details, testing conditions, equipment used, and complete test data.
• Safety: While EN 6035:2015 defines testing procedures, it does not specify health and safety practices, leaving it to the user to establish and implement suitable precautions.

Applications

EN 6035:2015 is highly relevant across the aerospace industry, supporting:

• Material Certification: Verifying compliance of new fibre reinforced plastic materials for aircraft components, structures, and interiors.
• Quality Control: Providing standardized tensile tests to monitor consistency and performance in production batches of composite laminates.
• Research & Development: Supporting the evaluation of different fibre architectures (unidirectional, woven) and matrix systems when developing advanced aerospace composites.
• Performance Assessment: Assessing aged or environmentally exposed composites as part of life extension or failure analysis programs.
• Comparison of Materials: Allowing benchmarking between notched and unnotched properties, which is crucial for understanding damage tolerance and selecting optimum materials.

The methodology is focused on aerospace applications but can also be extended to other industries relying on high-performance composites, such as automotive, marine, or wind energy.

Related Standards

Implementing EN 6035:2015 may require reference to other related standards often cited in aerospace composites testing, including:

• EN 2374: Aerospace series – Glass fibre reinforced mouldings and sandwich composites – Production of test panels
• EN 2489: Aerospace series – Fibre reinforced plastics – Determination of the action of test fluids
• EN 2565: Aerospace series – Preparation of carbon fibre reinforced resin panels for test purposes
• EN 2743: Aerospace series – Standard procedures for conditioning prior to testing unaged materials
• EN 2823: Aerospace series – Determination of the effect of exposure to humid atmosphere on mechanical characteristics

These standards provide additional procedures for specimen preparation, environmental conditioning, and measurement methods, ensuring a harmonized approach throughout the testing of composite materials.
