Is there a difference between ballistic and penetration resistant fabrics and/or vests?
Yes, the two are very different and are designed to do two very specific functions. The two functions are: • To stop projectile penetration (ballistic resistance). • To stop pointed/sharp object penetration (stab resistance). Due to the physical capabilities of aramid fabrics or aramid composite structures used in each of the above two functions, neither one will work effectively for the other. The reason for this is due to the weave count. Typically fabrics are comprised with a specified crossover weave count that is measured by the square inch. The higher the count the tighter the crimp between crossover points. Stab resistant fabrics rely on extremely tight, closely packed crossover points. When enough layers (plies) of this very tightly wove fabric are combined, resistance to penetration from pointed hand deployed weapons is enhanced. Three characteristics of a weapon affect it’s capability to penetrate something: • It’s size and shape. • It’s hardness. • The final factor is the hu
