离散树脂成型复合材料的防刺与服用性能

Stab-resistant performance and wearability of composite materials made by discrete resin molding

为平衡防刺服的防刺性能及穿着舒适性,采用软硬结合的设计理念,提出了一种离散树脂成型复合材料的成型工艺。选用改性聚碳酸酯薄片,以离散状态按照设计图案黏结在涤纶与芳纶基布面料上制备柔性防刺复合材料,探讨不同种类离散树脂成型复合材料的防刺性能,并研究该复合材料的透气性能与弯曲性能。结果表明:芳纶基布离散树脂成型复合材料的穿刺强度是涤纶基布离散树脂成型复合材料的2倍;4层离散树脂成型复合材料与40层叠层芳纶平纹布的防刺性能相当,并显著降低了材料厚度和质量;离散树脂成型复合材料的柔软性能良好,且透气性能优异。

In order to balance the stab-resistant performance and the wear comfort of stab-resistant body armor,a new discrete resin composite molding process was developed based on the design concept combining of soft and hard sessions.Discrete modified polycarbonate particles were solidified on the polyester and aramid base fabric according to the designed pattern.The stab-resistant performance as well as the breathability and bending performance of different types of discrete resin composites were studied.The results indicate that the stab strength of the aramid composites is twice as high as that of the polyester composites.The stab resistance of 4 layers of discrete resin composites is similar to that of 40 layers of aramid woven fabric,and composites thickness and weight are reduced significantly.It is also found that the composite has good softness and excellent breathability.
