    Abstract
  • An open explosion loading experiment was designed for three differently laminated carbon fiber composite laminates to study the dynamic mechanical behavior of the laminates under different explosive masses and explosive distances. Based on two high-speed cameras, an experimental measurement system for high-speed three-dimensional deformation field was built, and the images of the dynamic deformation process of the laminates under the action of the explosion were recorded. The dynamic displacement field and strain field of the laminates under the shock wave were calculated by 3D-DIC software. The results show that the laminates only undergo elastic deformation under low shock wave, and the orthogonal layer and the quasi-homogeneous layer have good impact resistance; under the action of high shock wave, the laminates will cause damage in the form of delamination, matrix cracking, fiber breakage, etc. The order of the layup has a great influence on the form of damage.
