The design of stab-resistant fabric requires identification of the threats, selection and combination of materials, and the analysis for the physical properties of unit components so that a final protective gear can effectively resist these threats. Therefore this study evaluates the stab-resistant property of aramid fabric and aramid/glass fiber hybrid fabric reinforced with LDPE thermoplastic resin. The stab-resistant strength for the different treatments was investigated, and the stab-resisting behavior depending on the shape of the impactor was also evaluated. In result the stabresisting behavior of aramid stab-resistant fabric reinforced with thermoplastic resin when impacted with a knife impactor is classified into a penetration step with maximum stab-resistant strength, cutting step, and the destruction step of accumulated fiber bundles. Also, when impacted with a spike impactor, all samples show a maximum stab-resistant strength on the initial penetration step and have low stab-resistant strength after initial penetration regardless of the reinforced resins. Therefore, in order to achieve maximum stab-resistant performance, it is concluded that optimizing the stab-resistant strength on initial penetration is essential.
