SAE AMS 3892/3C:2016 PDF Download

The SAE AMS 3892/3C:2016 standard describes a specific type of carbon fibers used for structural composites. These carbon fibers are continuous multifilament fibers and are available in the form of a tow or yarn, which may be twisted. The weight per unit length of the tow or yarn is determined by the filament count, which is indicated by the supplier's grade or material designation.

The specific variant covered by this standard is designated as GF 400 (2758), indicating a tensile strength of 40 ksi (276 MPa) and a tensile modulus of 40 Msi (276 GPa). The standard provides requirements for the physical and mechanical properties of the carbon fibers, including dimensions, tensile strength, tensile modulus, and other characteristics. It also includes testing methods to evaluate the compliance with these requirements. This standard ensures that the carbon fibers used in structural composites meet specific performance criteria for strength and stiffness, allowing for reliable and consistent manufacturing of composites.
