A PERMEABILITY DATABASE FOR COMPOSITES MANUFACTURING

The National Institute of Standards and Technology (NIST) has develope d a database containing a set of permeability results from carefully c ontrolled measurements for both saturated and unsaturated flows in gla ss fabrics. The materials studied are fully documented in the database , and in some cases the material compressibility is also included. The experimental techniques used to generate the permeability data are br iefly described and the included permeability data summarized. A sampl e search is illustrated to demonstrate the database user interface and the extent of the data documentation.
