Abstract
In this paper, the process of manufacture of template for lattice cylindrical composite is studied and lattice composite samples has been manufactured by the filament winding process. Also, the structural behavior of lattice cylindrical composite made by glass/Epoxy with triangular cells has been studied under high velocity impact by experimental and numerical analysis. A gas gun testing machine has been used for high velocity impact test that recorded the input and output velocities. Also, for this test, suitable fixture has been designed. The cylindrical projectile with spherical head has been used as impactor. Numerical simulation of impact tests has been conducted by ABAQUS commercial finite element code and the results have been verified by experimental results. Output velocity, surface damage, the separation between the shell and the rib are compared experimentally and numerically. Finally, numerical investigation of the shape of the projectile and the layup orientation has been done. Results show that 45 degrees angle of layup has minimum output velocity and maximum energy absorption. Also, the projectile with flat head has been created maximum area damage, because of the less area contact with shell relative to another projectiles, therefore has less output velocity and more energy absorption.
