YO259-15 REQUEST DATE. March. 1986 REQUESTER.. J. Latsko TEST DATES 3/6/86/ and 3/17,/86 TECHNICIAN(S) APPROVED BY. RfiggjL-gfflifch- REPORT DATE. TEST STAND_ April. 1986 V Friction Naterialr- ' Test Machine 1.0 PREFACE l Japan Fawick is using FP-500 non-asbestos friction '.material:, and they have requested an Airflex evaluation of said material..,; Accordingly, the objective herein is to compare .,s%the ,/performance/wear characteristics of this material to ' both i the* established characteristics of the standard (asbestos base) .yc jfrlction material, and also to the Japan Fawick supplied FP-r'500 data, .1 2.0 INSTRUCTIONS: _* ~ . ; C ' S j/ Using the Japan Fawick FP-500 friction .material, perform automatic cast iron drum driveline deceleration tests per the following: Drum test temperatures: 100 Degs F (wear-in thru stabilization), 300 Deg. F,:; 500 Deg. F, 700 Deg. F, and 100 Deg. F. Drum test speed: 3000 FPM initial velocity. Test stand inertia: 60 lb.-ft.sg. Applied pressure: 75 RSI 3.0 RESULTSr " .. .. - ' 3.1 AIRFLEX..DATAr J' % .; As depicted jpn the accompanying graphs, for the one speed/pressure condition tested, ,,-the FP-500 and NF-285 friction materials exhibited similar dynamic^and^htatie coefficients of friction, except that the NF-285 developed'approximately 100% coefficient on the first 100 Deg. F. cycle* while the FP-500 developed approximately 75% coefficient Under the same" conditions; conversely, the NF-285 developed approximately.25% less coefficient than the FP-500 at the 700 Deg. F test; condition. Also, per the above test procedures, the FP-500 friction Material provided approximately two to five times the wear life gf the NF--285 friction material for temperatures from 100 Deg. F through 500 Deg, F, with diminished, but basically equivalent wear lives' thereafter through 700 Deg. F. - e\ - :i FAW 10548
