Method for measuring amount of residual resin material in porous metal body

Abstract:

A differential thermal analysis of a plurality of metal-resin-containing layers, the resin material amounts of which are known and different from each other, is carried out. Heights of sample peaks observed at one temperature in the differential thermal analysis are measured, and a correlation between the resin material amounts and the sample peak heights is obtained. Then, a differential thermal analysis of a porous metal body is carried out, and a height of a peak observed at the same temperature is measured. An amount of a residual resin material in the porous metal body is obtained based on the measured height and the correlation.
