Abstract:
The objective of this work was to evaluate the influence of photodegradation by ultraviolet radiation on epoxy matrix composites reinforced with mallow/jute hybrid fabric in the energy absorption capacity against .22mm caliber projectiles. This ballistic efficiency was evaluated by the residual velocity technique. Exposure to UV radiation with both 75 h and 225 h caused changes in composite plates color, and optimized energy absorption capacity at level I events by NIJ 0101.04 standard, absorbing about 93% of the projectile energy, showing to be a technique fairly easy and fast to improve the ballistic properties of composites which in turn are economically more viable than the commonly used synthetic materials.
