ABSTRACT:
Disclosed herein is an apparatus for measuring adhesive and frictional properties of a polymer hemisphere relative to a contact plate provided in the apparatus. The apparatus comprise a body having a movable table installed to move along an X-axis and Y-axis and a vertical column positioned at a rear side of the movable table, a sample mount provided on the movable table and having a mirror to reflect surface images of a horizontal contact plate, a head assembly located at a front side of the column and having a polymer hemisphere used to press a surface of the contact plate to implement an adhesive force test, a camera device located at a front side of the mirror to capture the surface images of the contact plate during the adhesive force test, and a control device for analyzing various data inputted thereto during the adhesive force test.
