SAE AMS3853B-1995 PDF

Full title and description

SAE AMS3853B — Cord, Aromatic Polyamide, Nonmelting. Material specification for aromatic polyamide cord intended for aerospace applications; defines material form, characteristic requirements and related detail specifications for nonmelting aromatic polyamide cord.

Abstract

This AMS document specifies requirements for an aromatic polyamide cord (nonmelting) used in aerospace assemblies where heat resistance and dimensional stability are required. The B revision records administrative and technical changes to prior revisions; the document has since been made noncurrent/cancelled and later administratively superseded by other AMS actions.

General information

• Status: Cancelled / Noncurrent (administratively superseded in later AMS listings).
• Publication date: October 1, 1995 (AMS3853B revision date).
• Publisher: SAE International (Aerospace Materials Division).
• ICS / categories: Fabrics and textiles; Polymers; Heat-resistant materials; Aerospace materials specifications.
• Edition / version: Revision B (AMS3853B).
• Number of pages: 1 (short material specification / detail sheet).

Scope

This specification covers an aromatic polyamide supplied in cord form identified as nonmelting for aerospace use. It provides material identification, characteristic requirements and references to supplementary detail sheets for different cord strengths/sizes (AMS3853/1B, AMS3853/2B, AMS3853/3B and related detail specifications). The AMS entry notes that the specification was cancelled/noncurrent and later folded into AMS management actions.

Key topics and requirements

• Material: aromatic polyamide chemistry intended to resist melting and maintain performance at elevated temperatures.
• Form: cord — specified sizes/strength levels provided in detail sheets (example detail parts: /1B, /2B, /3B for specific strength ratings).
• Mechanical characteristics: tensile strength and energy/elongation requirements appropriate to cord class.
• Material identification and marking for aerospace traceability.
• Reference to test procedures and acceptance criteria for cord supplied to the aerospace industry.

Typical use and users

Used by aerospace manufacturers, materials engineers, quality and purchasing personnel specifying or procuring specialty cords for thermal/structural applications (e.g., seals, assemblies, harness supports or other items where a heat-resistant, nonmelting aromatic polyamide cord is required). Also of interest to suppliers and testing laboratories supporting aerospace contracts.

FAQ

Q: What is this standard?

A: SAE AMS3853B is an Aerospace Material Specification titled "Cord, Aromatic Polyamide, Nonmelting" — a short material specification that defines requirements for aromatic polyamide cord used in aerospace applications.

Q: What does it cover?

A: It covers the material definition, form (cord), characteristic requirements (tensile/energy ratings by detail sheet), identification and acceptance criteria for nonmelting aromatic polyamide cord. Specific strength/size variants were published as detail sheets (for example AMS3853/1B, /2B, /3B).

Q: Who typically uses it?

A: Aerospace manufacturers, procurement and quality engineers, suppliers of specialty cords, and test laboratories working to aerospace material requirements.

Q: Is it current or superseded?

A: AMS3853B is listed as cancelled/noncurrent in SAE records. Administrative listings indicate later AMS management actions and that the AMS3853 family continues in SAE cataloging; some distributors note an administrative supersession toward AMS3853 (administrative updates vary by source). Users should verify current status with SAE International before specifying or procuring.

Q: Is it part of a series?

A: Yes — AMS3853B is part of the AMS3853 family with associated detail sheets (AMS3853/1B, /2B, /3B) that cover specific cord strength and size variants. The base AMS3853 entry and prior revisions (AMS3853A, AMS3853) are part of the historical document chain.

Q: What are the key keywords?

A: Aromatic polyamide, nonmelting, cord, aerospace, AMS3853B, SAE International, heat-resistant textile cord.
