Product Code:SAE AMS3892/3
Title:Tow Or Yarn, Carbon (Graphite) Fibers - for Structural Composites, Gf 400 (2760) Tensile Strength, 40 (275) Tensile Modulus
Issuing Committee:Ams P Polymeric Materials Committee
Scope:This specification covers one type of continuous multifilament carbon fibers in the form of a tow or yarn (when twisted). The weight per unit length of the tow or yarn is governed by the filament count which is identified by the supplier's grade or material designation. Carbon tow or yarn, derived from a polyacrylonitrile precursor, with typical 400 ksi (2758 MPa) tensile strength and 40 Msi (276 GPa) tensile modulus for use in general purpose structural composites requiring high tensile strength and moderately high modulus of elasticity in tensionProduct Code:SAE AS7245
Title:Inserts, Screw Thread, Helical Coil 19cr 9.2ni, Corrosion Resistant Steel, Procurement Specification For
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope:This specification covers closely-wound helical coil, screw thread inserts made from a corrosion resistant steel formed wire of the type identified under the Unified Numbering System as UNS N30400. The inner surface of the insert coil, after assembly into a screw thread tapped hole, provides internal threads of standard 60掳 Unified form.
