SAE AMS 3892/7B:2016 PDF Download

SAE AMS 3892/7B:2016 is a standard that specifically applies to carbon fibers used in structural composites. This standard defines the requirements for carbon fibers with a tensile strength of 400 ksi (kilopounds per square inch) and a tensile modulus of 33 Msi (million pounds per square inch). These carbon fibers are typically used in applications where high strength and stiffness are required.

The standard specifies that the carbon fibers can be in the form of a tow or yarn. A tow refers to a bundle of individual carbon filaments, while a yarn refers to a tow that has been twisted together. 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 purpose of this specification is to provide a set of standardized requirements for carbon fibers used in structural composites, ensuring consistent quality and performance.
