New Test Device for Porous Media
Departmental lab is home to a new air permeability test apparatus. We are now able to determine the permeability of a wide spectrum of porous materials (for example, nonwoven fabrics,
weaves, knits, crochets, foams) because of the device’s large measuring range. In future combination with the existing DMTA (dynamic-mechanic-thermal analysis) test unit, material characterizations with flow and structural mechanics will be possible from a single source. In particular, it enables us to investigate the relationships between mechanical deformation and the associated changes in flow resistance.
