Impact experiments on fiber reinforced composite (FRC) strips enable to isolate interactions between plies and tows and reveal fundamental physics involved in impact on larger-scale FRC structures. In this work, a reverse- impact experimental technique was adopted to impact S-2 glass/SC-15 composite strips onto stationary projectiles at velocities ranging from 45 m/s to 450 m/s. Impact by three types of projectiles was investigated when the projectile nose diameter was 4 μm, 40 μm, and 400 μm, respectively. Real-time mechanical behavior of composite strips was captured by a high-speed camera. For each projectile type, different failure mechanisms were observed at various impact velocities and critical velocity of the FRC strip was identified. Effect of projectile nose diameter on failure of FRC strips was evaluated by inspecting variation of morphologies of strips during impact and comparing different critical velocities. Such reverse impact strategy allowed to focus on stationary projectiles and made the strip morphologies always appear within the camera window, which is deemed useful to integrate with high-resolution imaging setup and identify microscale perforation mechanism of composite strips by different projectiles in the future work.
