Abstract

This study was a prior study to establish the shelf life of bulletproof helmets, considered the aging factor of bulletproof helmets. To estimate the aging factor of bulletproof helmets, we established a hypothesis that the 'temperature' factor would have the greatest impact on the shelf life of the bulletproof helmet, considering the environmental treatment of the American army's bulletproof helmet's materials. To verify the hypothesis, high temperature acceleration environmental treatment of bulletproof helmets was performed, and the Arrhenius formula was applied to calculate the shelf life. The study result confirmed the negative correlation between bulletproof performance and high temperature, and the influence of temperature as an aging factor was not significant by deriving life by using the Arrhenius model. The limitation of this study is that we couldn't obtain enough samples due to the specificity (miliary supplies) of the test subjects. However, given that the life-related research on bulletproof helmets has not been carried out, this research has great implications and could be used as a reference for improving the Korean Army's bulletproof helmet specifications.

본 연구는 방탄헬멧의 저장 수명을 설정하기 위한 선행연구로 방탄헬멧의 노화인자에 대해 고찰해보았다. 방탄헬멧의 노화인자를 추정하기 위해 미군 방탄헬멧 구매요구서상의 환경 처리, 재료의 재질 등에서 공통적으로 요구하는 환경 처리에 관한 내용을 고려하여 '온도' 인자가 방탄헬멧의 수명에 가장 많은 영향을 미칠 것이라는 가설을 수립하였다. 이 가설을 검증하기 위해 방탄헬멧의 고온 가속 환경 처리를 수행하고 아레니우스 식을 적용하여 고온에 따른 수명을 산출하였다. 본 연구의 결과로 방탄성능과 고온 환경 처리 간 음(-)의 상관관계를 확인했으며, 아레니우스 모델을 활용하여 수명을 도출해냄으로써 노화인자로서의 온도의 영향성은 크지 않음을 확인하였다. 본 연구의 한계점으로 시험 대상이 가지고 있는 특수성(군수품)으로 인해 다양하고 많은 시료수를 확보하지 못했다는 것을 들 수 있다. 하지만 방탄헬멧의 수명 관련 연구가 진행되지 않았음을 고려할 때 이에 대한 선행연구를 수행했다는 데에서 본 연구가 시사하는 바가 크다고 할 수 있으며, 한국군 방탄헬멧 규격의 개선에 대한 검토 자료로서 활용될 수 있을 것으로 기대한다.
