Effect of fiber Volume fraction and Fiber Distribution on the Strength of FRP

Abstract

In this paper, investigations were made on the roles of fibers to the fracture behavior of the fiber reinforced plastics (FRP), which are widely known as one of the “Tailored Materials”, with special attentions of crack generation and its growth closely related to the fracture toughness value. As the results, it was found that the fracture behaviors of FRP are affected by not only the fiber volume fraction but also the dispersed state of fibers in the matrix resin, and also that scatters of the fracture strength are fundamentally attributable to the latter.
