SCOPE:1.1 Form: This specification covers parallel-yarn ropes formed from impregnated aramid fibers.1.2 Application: Primarily for nonconductive tension elements in antenna-supports.1.3 Classifi

8、cation: The ropes are classified by size, based on the nominal diameter of the finished rope as shown in Table I.2. APPLICABLE DOCUMENTS: See AMS 3813.3. TECHNICAL REQUIREMENTS: 3.1 Basic Specification: The complete requirements for procuring the ropes described herein shall consist of this document

9、 and the latest issue of the basic specification, AMS 3813.3.2 Material and Construction: The rope shall consist of aramid fiber constructional yarns gathered together in a parallel arrangement without twist, and covered with a braided jacket. The yarns shall be impregnated with an elastomeric formu

10、lation, filling the interstices between the yarns and between the yarns and the jacket so that the yarns are flexibly bonded to each other and to the jacket.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IH
