Abstract

Today, people working on rivers and seas such as fishermen, fishery inspectors, customs officers, etc. need a device that is both anti-drowning and anti-piercing. In this study, laminated composites made of woven fabric (para-aramid 495de), spectra shield (Dyneema® SB21) and floating foam were tested to develop a stab-resistance life jacket. Experiments were carried out to determine the appropriate number of layers and arrangement of laminated composites for stab-resistance up to protection level 1 according to NIJ standard (NIJ Standard 0115.00). Experimental results show that, considering the criteria of thickness and weight of laminated composites, the use of both woven fabrics and spectra shields will give the best results; followed by using only woven fabrics, and finally using only spectra shields. In the above 3 cases, placing the anti-piercing material on top of the floating foam will have a better stab-resistance effect than placing it under the floating foam. This is the base for manufacturing stab-resistance life jackets for those who work specifically on rivers and seas.
