Effects of Short Fiber Reinforcement on the Local Damage of Concrete Plates under High Velocity Impact Loading

摘要

This study presents the effects of short fiber reinforcement on the local damage of concrete plates subjected to high velocity impact. In a series of tests, three short fiber composite materials were used. Firstly, static bending tests were conducted to reveal mechanical properties in tension of the short fiber reinforced concrete. Then, high velocity impact tests were carried out to examine the effects of short fiber reinforcement on the local damage of concrete plates. Failure mode and strain behavior on the back surface of the short fiber reinforced concrete plates demonstrated that short fiber reinforcement was very effective in reducing the local damage.
