MERCURY INTRUSION POROSIMETRY (MIP)

What is MIP?

Pores or voids are unavoidably produced in composites during curing.  Their introduction must be limited due to their detrimental effects on mechanical properties and on fluid uptake by the cured composite.  MIP is used to determine void and fibre content in composites.  In the MIP method, mercury is forced to penetrate into porous samples under stringently controlled pressures.  Pressure measurements taken during the test provide data on the volume and size of the pores and the density of the cured composite.
