SCOPE:1.1 Form: This specification covers one type of continuous multifilament carbon fibers in the form of a tow or yarn (when

5、 twisted). The weight per unit length of the tow or yarn is governed by the filament count which is identified by the suppliers grade or material designation.1.2 Classification: Carbon tow or yarn, derived from a polyacrylonitrile precursor, with typical 400 ksi (2758 MPa) tensile strength and 40 Ms

6、i (276 GPa) tensile modulus for use in general purpose structural composites requiring high tensile strength and moderately high modulus of elasticity in tension.2. APPLICABLE DOCUMENTS: See AMS 3892.3. TECHNICAL REQUIREMENTS: 3.1 Basic Specification: The complete requirements for procuring the carb

7、on tow or yarn described herein shall consist of this document and the latest issue of the basic specification. 3.2 Storage Life: The product shall be readily strippable from the spool and the filaments spreadable when tested at any time up to six months from date of receipt by purchaser provided it

8、 has been stored at room temperature in the original closed container.AEROSPACE MATERIAL SPECIFICATIONAMS 3892/3B Issued NOV 1972Revised OCT 1992Reaffirmed MAY 2005Superseding AMS 3892/3ACopyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking per
