碩士 === 國防大學理工學院 === 兵器系統工程碩士班 === 104 === The goal of this study is to explore ballistic resistance capability of ceramic/fiber composite with different kinds of materials. After the combination of composite with optimal ballistic performance obtained, the best thickness ratio of the ceramic and fiber was further investigated. The ballistic tests were performed by using 0.30" Armor Piercing (AP) bullets. Assuming that the kinetic energy loss of projectile equals the energy absorption of target plates, the regression equation of target thickness and ballistic resistance capability by regression analysis was established. The optimal thickness combination of ceramics/fiber composite material under the constraint of areal density, total thickness and ballistic resistance capability was obtained by using MATLAB. Finally, the finite element software LS-DYNA was also used to perform a simulated analysis on the penetration performance. The results from simulation were then compared with the experimental results to verify the reliability. Through the experimental research, SiC and Dyneema fiber laminate showed the best ballistic resistance capability with lightweight. Under the considerations of areal density 1.938 g/cm2 to 2.946 g/cm2 and total thickness 0.9 cm to 1.5 cm, the energy absorption reflection curve of composite with different ceramic/fiber thickness variation was created. Furthermore, the best energy absorption per unit area density was calculated with both the thickness of SiC and Dyneema 7 mm in this study.
