Analysis of the Bulletproof Mechanism and Peridynamic Theory of Fiber-ceramic Composite Panels
Fiber ceramic composite target plates can meet the demand for lightweight protection,and are currently a trend in the research and use of lightweight protective materials in various types of protection,such as military,police,and aerospace.This article explores the characteristics of bulletproof ceramics commonly used in the development of protective structures;The type and mechanical properties of fibers;The respective forms of action of ceramics and fibers in the ballistic process.The relationship between the total energy dissipation of the composite structure and the formation of damage is deduced by applying the micro potential energy and the dissipated strain energy of the Peridynamic theory,and then the motion trajectory of the Peridynamic theory related to the bullet target action is obtained.By comparing the test results of the ballistic performance with the analytical results of Peridynamic theory,it is finally clarified that fiber constrained ceramic coating can improve the ballistic effect of the overall structure,It can fully utilize the ballistic resistance of ceramics.
