摘要： The present invention relates to a ballistic cloth using a unidirectional aramid sheet and a polyethylene film and a method for manufacturing the same and, more particularly, is characterized in that aramid multifilament layers, which have monofilaments stacked and arranged in one direction, are arranged perpendicularly, a polyethylene film, which plays both the role of a binder and the role of protecting the sheet surface, is arranged between the aramid multifilament layers to manufacture a ply, and the ply is inserted into a mold and undergoes a pressing process and a cooling process, thereby manufacturing a ballistic cloth. A ballistic cloth manufactured by the method according to the present invention is advantageous in that use of a polyethylene film having a low softening point between unidirectional aramid sheets improves adhesiveness between the sheets and also improves the slip factor when the same ply is stacked, thereby exhibiting excellent ballistics performance. In addition, since the binder is solely made of a film, odor-free, environment-friendly manufacturing processes can be employed, no freezing is needed during storage; improved flexibility of the sheet facilitates delivery and distribution of impacts of bullets when the ballistic cloth is worn, thereby improving the ballistics performance and making the ballistic cloth further lightweight; and the polyethylene film, which is the protective layer of the unidirectional aramid sheets, has an adhesive strength of at least 2kgf, thereby improving the ballistics performance.
