In this study, we used the unidirection fabric plied and crossed with high-strength aromatic polyamide fiber and high molecular weight polyethylene to make a non-woven fabric film. This research has two parts to discuss: the first part is making the unidirection fabric plied with 0 degree and 90 degree non-woven fabric film to carry out falling-ball impact strength and tensile strength test. The second part is changed the high-strength aromatic polyamide fiber and high molecular weight polyethylene piled number to give a bullet shooting test. When the Aromatic polyamide fiber non-woven fabric piled with 17, it can protect NIJ ШA test, and the high molecular weight polyethylene piled with 30 can also protect NIJ ШA test.
