聚氨酯复合芳纶织物的防刺性能
Stab resistance of polyurethane/aramid composite fabric
摘要
Abstract
In order to prepare the material with good stab resistance, the polyurethane/aramid composite fabric was pre-pared. The effects of coating processes, polyurethane types and superposition structure on the stab resistance of composite fabric were discussed. The results show that compared with the processes of wet coating and directly dry coating, the composite fabric using transfer coating process has better stab resistance. Coating with high modulus polycarbonate type polyurethane the stab resistance of composite fabric has been significantly improved, and the penetrated layer number in dynamic penetration test is only 31, and the stab resistance of composite fab-ric is further enhanced by bilaterally coating process, and the penetrated layer number reduces to 27. Under the same surface density, the superposition structure of 5 layers aramid fabrics up and down and 20 layers composite fabrics in the center has better protection effect, and the lower 5 layers aramid fabrics have not been scored.关键词
