Overview
ISO 13002:1998 establishes a systematic designation system for filament yarns made of carbon fibre, providing a clear and standardized approach for identifying and specifying these materials. Published by the International Organization for Standardization (ISO), this standard applies specifically to continuous filament yarns of carbon fibre used as reinforcement in polymer composites. It distinguishes materials based on key properties, aiding manufacturers, specifiers, and users in clear communication across international markets.
Key Topics
-
Scope and Applicability
- The designation system applies strictly to filament yarns of carbon fibre for polymer composite reinforcement.
- It is not applicable to discontinuous fibre products such as staple yarns, woven fabrics, braids, knits, or mats.
-
Classification Criteria
- Tensile Modulus of Elasticity: Provides information about the yarn's stiffness.
- Tensile Strength: Indicates the maximum stress the yarn can withstand before breaking.
- Linear Density: Represents the mass per unit length (tex), crucial for processing and performance.
-
System Structure
- The designation includes blocks that identify:
- The type and precursor of the carbon fibre
- Numeric codes for designatory properties
- Optional additional specifications for specific applications
- This structure ensures consistency in how filament yarns are described.
-
Limitations
- Materials sharing the same designation do not necessarily guarantee identical performance.
- The standard does not supply engineering or processing data; users should refer to applicable specifications and quality assurance documents for further details.
Applications
Adopting ISO 13002 provides practical benefits in industries where carbon fibre filament yarns are essential, including:
- Composite Manufacturing: Ensures reliable material selection for high-performance composite structures in automotive, aerospace, wind energy, and sporting goods.
- Material Specification and Procurement: Facilitates unambiguous ordering, inventory control, and quality assurance by providing clear product identification codes.
- Quality Control and Certification: Supports consistency in batch certification and compliance with recognized international requirements.
By following ISO 13002-compliant designation, organizations reduce the risk of miscommunication, improve traceability, and align with global best practices in carbon fibre supply chains.
Related Standards
For a complete approach to specifying and testing carbon fibre filament yarns, consider using ISO 13002 alongside other key ISO standards:
