General Information
Overview
EN 2563:1997 is a European standard developed by CEN that defines the test method for determining the apparent interlaminar shear strength of carbon fibre reinforced plastics (CFRP) in unidirectional laminate form. This aerospace series standard focuses on specimens with fiber orientation aligned parallel to the specimen length, emphasizing the material’s shear properties critical for high-performance aerospace applications. The specification uses a flexural test to evaluate the shear strength between laminate layers, providing essential data for quality control and material design.
Key Topics
- Material Focus: Carbon fibre reinforced plastics (CFRP) used as unidirectional laminates
- Test Method: Flexural testing to measure apparent interlaminar shear strength
- Specimen Orientation: Length parallel to the fibre direction, critical for accurate shear characterization
- Performance Metric: Apparent interlaminar shear strength representing resistance to shear between laminate layers
- Industry Context: Aerospace applications requiring precise mechanical property data for structural integrity and safety
Applications
This standard is essential for engineers, material scientists, and quality assurance professionals working with carbon fibre composites in the aerospace sector. Practical uses include:
- Structural Design Validation: Ensuring CFRP laminates in aircraft components meet shear strength requirements
- Material Certification: Verifying batch-to-batch consistency for carbon fibre laminates used in aerospace manufacturing
- Research and Development: Supporting development of new carbon fibre composite materials with tailored interlaminar properties
- Failure Analysis: Investigating delamination and shear-related failures in composite aerospace structures
- Process Optimization: Refining lamination and curing processes to enhance shear strength performance
