SAE AMS 3892/8B:2016 PDF Download

The SAE AMS 3892/8B:2016 standard specifies the requirements for carbon fibers used in structural composites. Specifically, it focuses on a type of carbon fiber that is in the form of a tow or yarn, with the option to twist the yarn. The weight per unit length of the tow or yarn is determined by the filament count, which is denoted by the supplier's grade or material designation.

These carbon fibers are intended for use in structural composites, where high tensile strength and modulus are required. The standard establishes the minimum tensile strength and modulus values for these carbon fibers, specifically at a level of 400 ksi (kips per square inch) or 2758 MPa (megapascals) for the tensile strength, and 40 Msi (million pounds per square inch) or 276 GPa (gigapascals) for the tensile modulus.

By conforming to the requirements detailed in this standard, manufacturers can ensure the consistent performance and quality of the carbon fibers used in their structural composites. This allows for reliable and predictable behavior in the finished composite materials, which is critical for applications that demand strength, stiffness, and durability.
