Standard Test Method for Density of High-Modulus Fibers

Importancia y uso:

5.1 Fiber density is useful in the evaluation of new materials at the research and development level and is one of the material properties normally given in fiber specifications.

5.2 Fiber density is used to determine fiber strength and modulus of both a fiber bundle and an individual filament. These properties are based on load or modulus slope over an effective area. Fiber density may be used with lineal mass of the fiber to give an approximation of effective tow area. Tow area divided by the average number of filaments in a tow gives an approximation of the effective area of an individual filament.

5.3 Fiber density is used as a constituent property when determining reinforcement volume and void volume based on reinforcement mass and laminate density.
