Ice Friction Tester
Background
Professor Sungho Jin of the University of California San Diego has developed a nano-structure of the polymer PEEK (Polyether ether ketone) that when applied to a silicon wafer makes the sample “super hydrophobic”. Super-hydrophobicity is defined when the contact angle of a water droplet on the material exceeds 150°. Professor Jin has the hopes of applying this material to the bottom of skis or ice skates to reduce the amount of friction due to capillary drag from the snow or ice In order to test the practicality of this, Professor Jin would like a friction tester which can measure the coefficient of friction and the wear of the nanostructure on ice.
Statement of Requirements
The device must be able to effectively measure kinetic friction of various low friction materials on ice.
The device must be able to run continuously or extended periods of time to test the effects of wear on the material.
The tester must be able to sustain a velocity of 2m/s (about 4.5 mph).
The temperature enclosed housing must be able to operate down to -20° C.
Must be reasonably easy to calibrate and repeat measurements.
Measurements must be distinguishable from unwanted noise.
