In this study, samples were prepared with resorcinol–formaldehyde–latex (RFL)‐coated continuous basalt fiber (CBF) cords and a natural rubber (NR)/styrene–butadiene rubber (SBR) matrix for interfacial fatigue tests under periodic radial loading conducted using a De Mattia Rubber Flexometer. The effects of the RFL formula on the interfacial fatigue behavior, including the fatigue life and the evolution of residual adhesion strength, were the focus of this work. The fatigue behavior was compared with that under axial loading. The results showed that under radial loading, the residual adhesion strength of the samples remained higher than that under axial loading, and the evolution of adhesion was divided into three stages. The adhesion improvement in the second stage was due to further cocrosslinking between the rubber matrix and the latex in the RFL layer, and the duration of the second stage was determined by the amount of reactive latex in the RFL layer. © 2018 Wiley Periodicals, Inc.
