ABSTRACT:
A method for evaluating a degree of dispersion of an inorganic material in a composite material comprising an organic material having dispersed therein the inorganic material, the method comprising the steps of: forming a block sample of the composite material; dividing the block sample into a plurality of unit volume pieces; incinerating each of the unit volume pieces under an oxidative atmosphere; quantitatively determining the ash content of each of the unit volume pieces; and calculating the scatter of the inorganic material content within the plurality of unit volume pieces.
