A permeability database for composites manufacturing

The National Institute of Standards and Technology (NIST) has developed a database containing a set of permeability results from carefully controlled measurements for both saturated and unsaturated flows in glass 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 briefly described and the included permeability data summarized. A sample search is illustrated to demonstrate the database user interface and the extent of the data documentation.
