Effect of Carbonized Ramosissima Nanoparticles on Mechanical Properties of Bamboo Fiber/Epoxy Composites

Abstract

Carbonized ramosissima nanoparticles (CRN) were prepared from ramosissima, a special plant in Ningxia, using a tube furnace and a ball mill. 0 wt%, 0.25 wt%, 0.5 wt%, 0.75 wt% and 1 wt% CRN were added to the resin. The composite was prepared by vacuum assisted resin perfusion (VARI) process. The effects of CRN content on the tensile, shear and low-speed impact properties of bamboo fiber epoxy resin composites were studied. The results showed that the tensile strength increased by 18.35% when CRN was 0.5 wt%.When CRN was 0.25 wt%, the short strength was the highest and increased by 38.96%. When CRN was 0.5 wt%, the plate peak load was the highest, the absorption energy was the lowest and the stiffness was the highest.
