Abstract

In this paper, the experimental behavior of grid cylindrical composite structures which are used widely in engineering structures under BALLISTIC IMPACT is investigated. In the present study, the grid cylindrical composite samples were manufactured by the filament winding process with fiber placement procedure and perforated by projectile using the ballistic gas gun. Input and output velocities of projectile were recorded. The results show that presence of discrete RIBS prevents spread damage from one cell to its adjacent cells and structure behaves differently against projectile with velocity near ballistic limit velocity and higher velocities. With approach to the RIBS location ballistic limit has been increased. However due to reduce FRACTURE AREA, overall and local deformations after impact in velocity which is higher than ballistic limit velocity, projectile has been come out from grid samples with higher velocity than simple composite shells. In this paper, delamination in outer composite shell and RIBS, debonding between shell and RIBS, residual velocity of projectile, FRACTURE AREA of the grid specimens and the effects of curvature in two deferent velocities were reported and commented upon as results.
