Abstract

Abstract

Bamboo scrimber is a new type of bamboo-based composite materials with outstanding mechanical properties which is more effective than some wood such as pine. In order to evaluate the impact mechanical properties of the bamboo scrimber along the grain under impact loading, this study made the samples by commercial bamboo scrimber as the research object with the density about 1.06 g/cm³ and the moisture content about 8.52%, manufactured by Moso bamboo with the age of 3−5 years. The quasi-static uniaxial compression, cyclic loading and unloading, and dynamic loading tests were all carried out to explore its loading deformation process, various mechanical performance parameters, and the strain rate effect under different strain rates, as obtained by the MTS universal material testing machine and the split Hopkinson pressure bar (SHPB) testing system, respectively. The results show that the compression process of the bamboo scrimber along the grain can be divided into an elastic deformation stage and an elastic-plastic deformation stage. The failure type of bamboo scrimber under compression load was ductile failure with much better energy absorption capacity than brittle failure. Its various strength indexes, including elastic ultimate strength, yield strength and failure strength showed high strain rate sensibility, all go up with the increase of the strain rate. A linear relationship exists between the dynamic increase factor (DIF) and strain rate, with a slope of about 0.0024. The strain energy density during the compression process of the bamboo scrimber also exhibits a linear relationship with the strain, and it increases with the increase of strain rate, indicating that the energy absorption capacity of bamboo scrimber increases with the increasing strain rate. In summary, as verified by tests, the impact mechanical properties of the bamboo scrimber along the grain are good and its strain rate effect is significant.
