This paper describes theoretical and experimental studies undertaken in connection with the problem of sampling carbon fiber aerosols in an ambient environment. Calculations indicate that carbon fiber aerosols with an 8-μm fiber diameter and a density of 1.8 g/cm3 can be sampled by a sampler designed to collect particles in the 10–30–μm aerodynamic diameter range if fibers up to a few millimeters in length are to be collected. An approach is then described in which carbon fiber aerosols are collected in the impactor of the inlet of a dichotomous sampler. Experimental data are presented showing that the impaction characteristics of the carbon fiber aerosol can be predicted with a reasonable degree of accuracy by approximating the shape of the fibers by a prolate ellipsoid.
