Anti-stabbing performance of laminated composite fabric

The conventional laminating and compositing process was employed to produce a laminated composition fabric which is consisted of spacer fabric / aramid laid fabric / aramid woven fabric. The antiballistic insert plate( aramid laid fabric / aramid woven fabric) currently for the police and different adhesives were used in making the above product whose anti-stabbing performance was investigated under quasi-static and dynamic conditions. The experimental results revealed that the aramid plain woven fabric,due to its tightness,can be used as the outer layer of the composite,as an effective anti-stabbing layer; the inner layer should be desiged tighter so that it will prevent the knife edge from going down; and while the yarns suspended beneath the outer layer can lock the edge of the knife efficiently to stop it going down continuously. In addition,The adhesive has greater impact on the anti-stabbing performance of the composite,therefore an adhesive with good strength,high tenacity and good cohesiveness should be used so as to enhance the anti-stabbing performances of the composite.
