Superseding AIR4567B

Composite Electrical Connectors

RATIONALE

AIR4567C is being stabilized because the information and guidelines are considered mature and the committee does not

anticipate future changes. Stabilization does not imply the information and guidance are unacceptable for applications for

which it is designed. Any changes noted by a user which results in an information or guidance change will be addressed by

a new revision.

STABILIZED NOTICE

This document has been declared “STABILIZED” by SAE AE-8C1 Connectors Committee and will no longer be subjected

to periodic reviews for currency. Users are responsible for verifying references and continued suitability of technical

requirements. Newer technology may exist.

FOREWORD

This SAE Aerospace Information Report (AIR) provides information and guidelines on cylindrical and rectangular

connectors and accessories with components manufactured from composite materials.

Electrical connectors and their associated accessories traditionally utilized aluminum alloy as the standard material for

component parts such as shells and coupling nuts. This document provides information on connectors and accessories

that utilize composite materials to replace the standard aluminum alloy components.

Composite connectors offer the user advantages over connectors constructed with aluminum components such as weight

savings and corrosion protection.

This document addresses factors that military connector specifications, configured for aluminum components, may not

clearly define and establishes guidelines for test requirements for specific applications.

General use connectors are designed to operate in severe environments typically associated with military defense

electronics and weapon systems and commercial aerospace applications. Qualification test requirements from these

environments have evolved and are defined in EIA 364. These assure the user that qualified connectors will meet those

demanding performance parameters. Evaluating connectors containing composite components using testing evolved

from experience with aluminum components may not identify stress factors associated with composite materials. The

testing designed to find flaws in aluminum components may also inadvertently over stress composite materials.

Composite connectors offer the designer an alternative material to connectors having their shell components

manufactured entirely from aluminum alloy for applications where weight saving and corrosion protection are desired.

Composite connectors are intended to replace aluminum connectors and be capable of meeting their established

performance parameters. See Section 4.

Composite connectors discussed in this document are connectors with shell components wholly or partly manufactured

from high temperature resins in lieu of aluminum alloys. The composite material is generally defined as thermoplastic or

thermoset resin mixed with a blend of strengthening fibers to achieve mechanical strength which is then metalized to

achieve electrical performance similar to plated aluminum alloy. The composite connector or accessory shell may include

a metal insert. The composite materials selected should be comparable to aluminum within the temperature realms

specified in general use applications, such as -55 to +150 °C, -65 to +175 °C, -65 to +200 °C, and -65 to +260 °C. The

design and construction of composite connectors is subject to the requirements of the connector specification. This

document recommends designs that utilize high temperature thermoplastic or thermoset resins, compatible to

metalization processes.

The effects of the following types of stress are known when applied to plated aluminum shell connectors, additional

testing should be considered for composite connectors:

SAE INTERNATIONAL AIR4567™C Page 2 of 12

a. Exposure to ultraviolet light

b. Weatherability

c. Flammability

d. Resistance to hydrolysis

e. Hygroscopicity

f. Outgassing properties in a vacuum environment

g. Fluid resistance

h. Resistance to atomic oxygen

i. Exposure to ozone

j. Vacuum stability

k. Shell electrical conductivity

l. Resistance to EMI/RFI/EMP

m. Resistance to indirect lightning strike

n. Toxicity and odor in a high temperature vacuum environment

o. Thread and bending strength at operating temperature

The purpose of this document is to provide information and guidelines that may not be clearly defined in the connector

specifications and define terms and technologies associated with composite materials as they relate to electrical

connectors and accessories.
