Property Estimation of Compound Armors by Small Sample Statistic Analysis

The critical non penetrating area density under different non penetrating probability and the critical penetrating velocity under different penetrating probability for different compound structure armors with a definite confidence level were presented by small sample two dimension up and down method based on many ballistic tests. The statistic analysis on experimental data of three kinds of compound armors was put forward and the critical penetrating velocity, smallest full penetrating velocity and largest non penetrating velocity with a definite confidence level of each compound armor were revealed. The ballistic performance dispensability of different compound structure armor was analyzed. The results are helpful to the design and application of compound armors.
