| Abstract: | To study the response characteristics of the carbon fiber fabric reinforced composites under impact loading, one dimensional strain impact test, multi gauge technique and Lagrange analysis method are used. The decaying rule of the stress σ , strain ε , strain rate ε˙ and density ρ with time and space is obtained. By the theory of dynamics, the impact response characteristics of the material is analyzed and discussed. |
