从各国防弹衣的研制状况可以看出,防弹衣的发展呈现出以下的趋势: 高新技术材料将得到更广泛的应用从防弹衣的发展历程可以看到,其性能的提高一直与高技术材料的应用密切相关。60年代末70年代初,“凯夫拉”(Kevlar)纤维的问世不仅代表着合成纤维技术史上一个新的里程碑,而且也给防 From the research and development of bullet-proof vests in various countries, it can be seen that the development of bullet-proof vests shows the following trends: High-tech materials will be more widely used From the development of bullet-proof vests, we can see that the performance improvement has always been related to high-tech materials Application is closely related. In the late 1960s and early 1970s, the advent of “Kevlar” fibers not only represented a new milestone in the history of synthetic fiber technology,
