Countries and countries in order to safeguard its own security, in response to the global war on terrorism, there is a need of high strength large number of UHMWPE (ultra-high molecular weight Polyethylene, referred UHMWPE) fiber produced bulletproof vests, helmets and other uses of the anti-puncture protective clothing.
In this study, based on the use of body armor by adding UHMWPE fabric layers, coating and laminating glue to do is to add various types PU cushioning materials to improve the armor on the part of the anti-puncture performance is weak, and do weight restrictions, in order to facilitate the performance of body armor comfort.
In the experiment, the first to explore the bonding adhesive force and to improve the use of adhesive bonding obtained after UHMWPE plastic and fabric between; after plasma treatment can improve the bonding adhesive bond, while having a bonding glue the role of decentralized power, when the fabric is attached gum paste more long time, the better it will force the dispersion effect.
Again in order to meet NIJ 0115.00 standard anti-puncture SPIKE CLASS 2, respectively, to 33 joules and 50 joules of force to puncture test and find out the optimal placement of different PU materials, and weight change, the results show that when PU layer is placed at the bottom, the power tool for the Friends of buffering the best results, the sample layers 7 layers, the weight of 2481 (g), and through the depth of 0.66 cm, and both can achieve the desired effect.
