Three-Point Bending Fracture Behaviors of Bamboo
Bamboo is a typical natural building material, which is longitudinally reinforced by robust fibers. This present paper focuses on the three-point bending fracture behavior of bamboo across and along fiber lengths with dense fiber layer upward and downward. The three-point bending strength of bamboo across the fibers is about ten times higher than that along the bamboo fibers, and the value of three-point bending strength with dense fiber layer downward is higher than that with dense fiber layer upward. Based on the microstructure of the fracture surfaces and the loading curves, different fracture processes are concluded to explain the anisotropy of bamboo.
