| Abstract Scope |
This study evaluated the impact resistance of a hybrid composite with an epoxy matrix reinforced by linen and aramid fibers. The composite panels were manufactured by vacuum-assisted hand lay-up. Subsequently, ballistic tests were performed using lead projectiles to determine energy absorption by the material. The results show that the linen-reinforced composite absorbed a greater amount of energy, although it presented delamination, while the aramid-reinforced composite demonstrated more consistent and reliable behavior, absorbing impacts uniformly. The combination of fibers provides a hybrid alternative to monolithic materials, particularly for applications that require both resistance and energy absorption. Improving the matrix-fiber bond emerges as a key consideration to minimize delamination and maximize composite performance. |
