Abstract
Stab resistance body armor (SRBA) is essential in protecting people from knife injuries. The protective parts of traditional SRBA are made of multi-layered ultra-high molecular weight polyethylene, which causes heavy heat stress for people wearing it. In this paper, the protective parts of SRBA were manufactured using laser sintering (LS) technology, which provide high manufacturing flexibility as well as high wearing comfort. Two different structures were investigated, one is squared plate and the other is pyramid. It was found the pyramid structure showed much higher stab resistance property then the plate, which is a result from the angle and thickness effects. This paper is the first effort applying the technology of LS and material of PA 3200 on SRBA, and by applying the pyramid structure on the protective layer of the SRBA, the total weight could reduce 30-40%.
