This paper deals with a study of the flexural behavior of thin, fiber-reinforced, resinoid abrasive disks. During use, these disks generally encounter a much higher ratio of flexural or bending stress to rotational stress than do straight grinding wheels. Material characteristics such as flexural modulus of elasticity, flexural strength, and flexural strain to fracture were evaluated for specimens machined from the disks at known orientations of each layer of fiber reinforcement. The effect of transverse loading on the abrasive disk was investigated by means of static flexural tests on randomly oriented disks. The failure load was predicted from considerations of beam theory and was found to agree well with experimental data.
