Aramid fiber is a strong, heat-resistant fiber formed of polymers with repeating aromatic groups branching from a carbon backbone. In the polyamide fibers, at least 85% of the amide linkages are attached directly to two aromatic rings. Two types of  Aramid materials are used in. Meta  Aramid paper which is used for making honeycomb core materials required for sandwich construction Para- Aramid fibers are made by the solution polycondensation of diamines and diacid halides. The oriented Para substituted aromatic units provide a rod like polymer. The rod like structure results in a high glass transition temperature and poor solubility. They are not spinnable by conventional process and hence they are made by the dry- jet wet spinning of liquid crystalline polymer solutions.

They are used in aerospace and military applications, for ballistic rated body armor Fabric and ballistic composites, High performance, low weight, flexible armour e.g. Body armour Flak jackets. Anti-ballistic composites e.g. mobile screens Helmets Spall linings Primary armour Insert plates Bomb blankets Vehicle armour.
