An analytical modeling for high-velocity impacts on woven Kevlar composite laminates

Abstract

Abstract. In this paper, an analytical model, which based on energy balance, is built to study the process of high velocity impacts on woven Kevlar composite laminates by a cylindrical projectile. Four different mechanisms, such as laminate crushing, linear momentum transfer and tensile fiber failure, and shear plugging, is absorbed by the laminate while impacting. Then, simplification of the model is done to obtain the residual velocity and ballistic limit. The analytical results are validated with the results of experiment, and the perturbation analysis is done to analyze the reason of error.

Experimental and Modeling Study on High Velocity Penetration of a Carbon/Epoxy Composite Laminate

“…Yahaya et al [11] have performed studies for the Kevlar-Kenaf hybrid woven composites and found that the energy absorption increased while the impact velocity declined. Chen et al [12] proposes a low cost model to predict the residual velocity of projectile after impacting on composite laminated plates.…”
