BULLET PENETRATION INTO BAMBOO, ORIENTED STRAND BOARD AND LOW-DENSITY FIBREBOARD TARGETS
Abstract
In previous work, we have discussed projectile penetration experiments into a variety of wooden targets, i.e. natural wood, and medium density fibreboard (MDF) targets. However, this paper will discuss normal projectile impacts on three different types of wood-based materials: bamboo, oriented strand board (OSB) and low-density fibreboard (LDF). Impact experiments have been performed using flat targets. Two different 9 mm projectiles are used: Ball and Ball Subsonic. Penetration depths of projectiles are determined using x-ray photography. The experimental data are analysed using the Poncelet model and the Robins- Euler model. As in previous work on wooden materials, penetration depths of the projectiles are related to physical properties of the target material. For bamboo, OSB, and LDF Janka hardness measurements have been performed. Results obtained are compared with earlier results on MDF and natural wood. Again, the observed dynamic strength R shows a good correlation with the Janka hardness.
