Significance and Use | ||||||||||||||
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 both of 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. |

1. Scope | ||||||||||||||
1.1 This test method covers the determination of the density of high-modulus fibers and is applicable to both continuous and discontinuous fibers. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard may involve
hazardous materials, operations, and equipment. This standard does
not purport to address all of the safety concerns, if any,
associated with its use. It is the responsibility of the user of
this standard to establish appropriate safety and health practices
and determine the applicability of regulatory limitations prior to
use.
