Bending Properties of Fiber Composite Dilatant Compound

Abstract

We have developed a viscoelastic-plastic dilatant compound, whose stiffness increases with increasing deformation rate, as a matrix material, and a "fiber composite dilatant compound" to which fibers have been added. In this study, three-point bending flexural tests were conducted to clarify the mechanical properties of the material. The results showed that the bending load increased when the fibers were oriented in the bending direction. It was also found that, under constant fiber content, lengthening the fibers and increasing the number of fibers by decreasing their diameter contributed to the increase in bending load.
