Analysis of Aramid Fabric Damage Mechanisms as a Result of Different Load Speeds

The study aramid fabrics of Twaron T750 type loaded in quasi-static punching and impact loading tests were tested. The scope of these works was carried out in the form of piercing with a non-deformable steel penetrator with a semi-spherical tip, moving at a constant low speed and on the drop impact test and firing the aramid fabric with a 9 × 19 mm Parabellum projectile. The areas of damaged yarns were subjected to microscopic analysis using the SEM technique. In this way, efforts were made to show that the speed of piercing is important in terms of the damage to the yarns of the individual fibers of the fabric. The obtained results were used to formulate guidelines for the design of energy-consuming structures.
