A Friction-Test Benchmark with Twintex PP

摘要

This paper presents an update on a friction benchmark, that was proposed during the 13~(th)ESAFORM conference. The goal is to compare different friction test set-ups [1-4] by determining the coefficient of friction (CoF) for Twintex? PP. The benchmark instructions are based on the ASTM standard D1894 [5] but also account for different friction velocities, pressures and temperatures. At the time of writing five research groups contributed to the benchmark, each with a custom designed test set-up, differing in size, mechanism, force control and temperature regulation. All tests will be conducted with woven glass reinforced polypropylene, from the same Twintex? batch. Conclusions will be drawn about the comparability of different testing methods by recognizing and analyzing systematically deviating results.
