Abstract:
An apparatus for testing static and kinetic frictional coefficients of the interface between a sample of a sheet material and a test medium, said apparatus comprising:a substantially horizontal platen for accommodating the test medium;a sled for accommodating the sample of sheet material;a pair of spaced, parallel rails for reversibly raising and lowering said sled relative to said platen such that said sled may be selectively placed on said platen with the sample of sheet material being in engagement with the test medium, said sled being formed for engagement with said rails;means for forcing translation of said sled across at least a portion of the test medium and across at least a portion of said platen; andload sensing means for measuring in real time the forces required to initially cause translation of said sled and for measuring in real time the forces required to maintain translation of said sled.
