METHOD AND APPARATUS FOR MEASURING STRENGTH RATE IN THICKNESS DIMENSIONS

摘要

An object of the present invention is to provide a method and an apparatus for measuring the stiffness in the thickness direction of a polymer film which can obtain accurate measurement values by applying a load continuously.;In order to realize this, in the present invention, a normal load is continuously applied to a sample cell in the absence of a test piece to obtain a deformation amount by converting a voltage through the LVDT, and then a load is applied to the test piece in a state where the test piece is placed, And a method and an apparatus for measuring the stiffness in the thickness direction of the polymer film to obtain the deformation and the load relation of only the test piece due to the difference of the deformation amounts.
