The coatings control the degree of asperity interactions by providing varying amounts of separation of the fiber and matrix phase. As the coating thickness is increased, from top to bottom, the asperity interaction(and the resulting radial misfit strain) is reduced (courtesy of D MumnP1: ARK/MBL/rkc P2: MBL/vks QC: MBL/agr T1: MBL May 16, 1997 13:47 Annual Reviews AR034-16 504 FABER Figure 2 Schematic illustration of the effect of fiber coatings on fiber sliding behavior.
