使用凯夫拉的防护产品可以防止子弹穿透保护层。不过,子弹力道的直接冲击虽有减轻但仍不可低估,它们在这方面的防护能力就要弱一些。
To solve this problem, such products typically require additional protective layers of metal inside Kevlar for reinforcement.
为解决这个问题,这些产品往往都需要在凯夫拉之内加装保护性金属层,以增强防护性能。
Many law-enforcement professionals, for whom such protection was designed, still find body armor cumbersome, uncomfortable and an impediment to their official day-to-day duties.
由于这种设计,很多执法人员仍然觉得防护装备穿起来又笨重又不舒服,对他们执行日常公务是一种妨碍。
According to the Federal Bureau of Investigation, 35.7% of the 541 U.S. police officers killed in the line of duty from 2001 to 2010 weren't wearing body armor.
据联邦调查局(Federal Bureau of Investigation)数据,2001年至2010年有541名警察在执行公务期间死亡,其中35.7%的人没有穿戴防护装备。
Non-Newtonian fluids could, for example, be combined with Kevlar or other materials to create lighter, more comfortable body armor products, removing the need for additional metal or ceramic coatings, according to companies that use the technology.
而将非牛顿流体与凯夫拉或者其他材料结合可以制造出更轻便、更舒适的防弹衣,而且不需要使用额外的金属或陶瓷夹层。
