SAE AMS 3892/1C:2016 PDF Download

The SAE AMS 3892/1C:2016 standard specifies the requirements for a specific type of carbon fibers used in structural composites. These carbon fibers are continuous multifilament fibers, which can be in the form of a tow or yarn when 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 standard establishes the minimum tensile strength and tensile modulus requirements for this type of carbon fibers. The tensile strength refers to the maximum stress that the fibers can withstand before breaking, while the tensile modulus represents the fibers' ability to resist deformation under tension. In the case of this standard, the specified minimum tensile strength is 400 ksi (kilopound per square inch), or approximately 2758 MPa (megapascal), and the minimum tensile modulus is 33 Msi (million pounds per square inch), or approximately 228 GPa (gigapascal).

These requirements ensure that the carbon fibers meet the necessary strength and stiffness properties for use in structural composites applications. Compliance with this standard allows manufacturers to confidently source carbon fibers that will satisfy the performance requirements of their composite materials, contributing to the reliability and durability of the final composite structures.
