Abstract: To investigate flexible,low-cost and well stab-resisting packaging material,the aramid fiber and nylon (PA6) and polypropylene (PP) staple fiber were employed to design nonwoven sandwich laminated anti-stabbing material which was composed of PP/PA6/aramid non-woven as surface layer,PA6 as middle layer,and PP/PA6 as bottom layer by interlayer reinforcing method.The tensile property and stab resistance of composite were investigated by changing the content of surface aramid fibers.The results showed that the tensile property and stab resistance increased linearly with the increase of surface aramid content.When the aramid content was 15%,the nonwoven fabric had the highest tensile load,knife-resistant and spike-resistant load,209.24N,83.52N and 126.85N respectively.The tensile and stab resistance increased linearly with the increasing of layer number,and the material achieved the best mechanical and stab protection when the layer number was three.Knife and spike resistance had different mechanism.Fiber fracture and fiber pushing were the mechanism for knife resistance and fiber pushing was for the spike resistance.
