Low velocity flexural impact behaviors of bamboo fiber reinforced composite beams

Low velocity flexural impact behaviors of bamboo fiber reinforced composite beams

To investigate the anti-impact behavior and loading rate sensitivity of bamboo fiber reinforced composite (BFRC) beams, low-velocity-impact flexural experiments were performed under impact velocity changing from 2 m/s to 10 m/s. Quasi-static flexural tests were carried out under the same conditions...
