Full title and description
SAE AMS3892/11B — Tow, Carbon Fiber For Structural Composites: 450 (3103) Tensile Strength, 32 (221) Tensile Modulus. This aerospace material specification defines the requirements for a single grade of carbon fiber supplied as tow intended for structural composite applications, giving mechanical property limits, quality assurance and packaging/delivery provisions.
Abstract
This specification covers one type of carbon fiber in the form of tow, defined by a nominal tensile strength of 450 ksi (≈3103 MPa) and a tensile (Young's) modulus of 32 Msi (≈221 GPa). The document is a stabilized AMS material specification issued by SAE International in December 2016 and used to specify raw fiber for high-performance composite manufacture.

Scope
The scope of AMS3892/11B is to specify a single grade of carbon fiber supplied as tow for use in structural polymer-matrix composites. It sets out the required mechanical properties (tensile strength and modulus), inspection and test requirements, acceptance criteria, and provisions for preparation for delivery (packaging, marking and documentation). The standard is intended for use where consistent fiber properties are required for critical aerospace composite parts.
Key topics and requirements
- Designation and material description: carbon fiber in tow form with specified strength and modulus.
- Minimum mechanical properties: nominal tensile strength 450 ksi (≈3103 MPa) and tensile modulus 32 Msi (≈221 GPa).
- Manufacturing and product form requirements: tow configuration, allowable coatings/size treatments (if specified), and handling instructions.
- Testing and inspection: tensile testing, lot acceptance sampling, and documentation of test results.
- Quality assurance and traceability: lot identification, certificate of conformance, and rejection/repair provisions.
- Preparation for delivery: packaging, labeling, and shipping conditions to protect fiber integrity.
Typical use and users
This AMS is used by aerospace OEMs, composite part manufacturers, material procurement specialists, quality/control engineers, and design engineers specifying raw carbon fiber for structural composite laminates. Typical applications include primary and secondary aircraft structures, rotorcraft components, and other high-performance composite parts where consistent high-strength, high-modulus fiber is required.
Related standards
Related documents include other parts of the AMS3892 family (for example AMS3892/10B and earlier AMS3892/11 and AMS3892/11A revisions) that specify different tensile-strength/modulus grades of carbon tow, plus broader composite material standards and test methods referenced by AMS documents. AMS3892/11B specifically supersedes AMS3892/11A as the stabilized 2016 revision.
