Full title and description

SAE AMS3783B-1995 — Glass Cloth, Chloroprene (Cr) Coated. Aerospace material specification covering a glass cloth substrate coated with a chloroprene (CR) polymer; this revision (B) was published/revised in 1995 and marked cancelled/withdrawn in October 1995.

Abstract

This short material specification defines the composition, coating type and minimum performance/test requirements for a chloroprene (CR) coated glass cloth intended for aerospace applications (insulation, protective covers, flexible barriers). Revision B was released in 1995 and the document was cancelled/withdrawn by the Aerospace Materials Division in October 1995.

General information

• Status: Cancelled / Withdrawn (canceled October 1, 1995)
• Publication date: October 1, 1995 (Revision B)
• Publisher: SAE International — Aerospace Materials Division (AMS P: Polymeric Materials Committee)
• ICS / categories: 59.080.40 (Coated fabrics); 59.100.10 (Textile glass materials)
• Edition / version: Revision B (AMS3783B, 1995); previous editions: AMS3783A (1991), AMS3783 (1986)
• Number of pages: 1 (AMS3783B revision record lists a single-page revision entry; earlier full AMS3783 documents show longer original specification content).

Key bibliographic and status records from SAE’s AMS catalog and reseller/catalog listings confirm the cancellation and revision history.

Scope

This specification covers one specific type of woven glass cloth coated with a chloroprene (CR) polymer coating. It sets out the intended material form (coated fabric), basic performance and test expectations appropriate to aerospace uses (electrical/thermal insulation and protective fabric applications), and applies to the defined grade(s) of CR-coated glass cloth described in the AMS text. The AMS entry for this product was cancelled in October 1995.

Key topics and requirements

• Substrate: woven glass cloth (electrical/structural glass fiber fabric) specified to textile/weight/finish parameters.
• Coating: chloroprene (CR) polymer coating applied to the glass cloth to provide insulation, abrasion resistance and environmental protection.
• Performance properties: minimum tensile strength, elongation, coating adhesion, and physical properties required for the specified grade (as detailed in the AMS text for the base specification).
• Test methods: referenced or specified tests for tensile, adhesion, and other acceptance checks appropriate to coated fabrics used in aerospace applications.
• Form and finish: roll lengths, widths and surface finish definitions typical for coated glass cloth materials intended for aerospace fabrication.
• Regulatory/legacy note: document was cancelled in October 1995; users should consult current AMS entries or alternative specifications for an active requirement.

Primary content descriptors and test/acceptance themes reflect the AMS specification family for coated glass fabrics.

Typical use and users

Typical users include aerospace OEM engineers and materials engineers specifying insulating or protective fabric materials, manufacturers and suppliers of coated fabrics, repair and maintenance organizations working to legacy specifications, and quality/inspection personnel who must verify material conforms to the referenced AMS requirement (or an applicable replacement). Because AMS3783B is cancelled, contemporary users should identify an active AMS or other governing specification before procurement or qualification.

Related standards

Related/previous documents in the AMS series: AMS3783 (issued April 1, 1986) and AMS3783A (revised October 1, 1991). Historical/industry equivalents or similar documents include legacy military specifications for coated glass fabrics (for example, MIL-C-7637 revision-series are cited as similar in commercial records). Users should compare the AMS family and applicable military or ISO/ASTM coated-fabric standards when seeking an active replacement.

FAQ

Q: What is this standard?

A: SAE AMS3783B-1995 is an Aerospace Material Specification titled "Glass Cloth, Chloroprene (Cr) Coated" (Revision B, 1995) that defined a chloroprene-coated glass fabric material for aerospace applications.

Q: What does it cover?

A: It covers a specific grade/type of woven glass cloth coated with a chloroprene (CR) polymer, including basic material description, required coating type, and the physical/performance characteristics and tests applicable to that coated fabric for aerospace use.

Q: Who typically uses it?

A: Aerospace designers and engineers, materials purchasers, coated-fabric manufacturers and quality/inspection personnel—particularly those working with legacy hardware or repair processes that referenced the AMS requirement. Because the document was cancelled, contemporary users should identify a current specification.

Q: Is it current or superseded?

A: AMS3783B is not current; it was cancelled/withdrawn in October 1995. The AMS3783 family has earlier revisions (AMS3783, AMS3783A) and users should consult SAE/AMS catalogs or equivalent active standards to find a current replacement or modern specifications.

Q: Is it part of a series?

A: Yes — it is part of the AMS3783 series for glass cloth, chloroprene-coated materials. The revision history includes AMS3783 (1986) and AMS3783A (1991) with AMS3783B recorded in 1995 (cancellation noted).

Q: What are the key keywords?

A: glass cloth; chloroprene; CR-coated; coated fabric; aerospace material specification; AMS3783; insulation; coated textile.
