The invention discloses a composite material for an automobile safety air bag cover, which comprises a fiber layer and a covering layer covering any one or two of the upper surface and the lower surface of the fiber layer, the fiber layer comprises at least one fiber unit, and the fiber units are arranged on the surface where the fiber layer is located in a left-right extending manner or in a left-right circuitous manner. The fiber units are arranged linearly or in a wave shape in the left-right direction; and the composite material is fixed on a cover cap of the automobile safety air bag. The composite material has high tensile strength in the left-right direction, when the safety air bag pops up, the composite material fixed to the shell panel of the safety air bag can prevent the shell panel from being broken to a large extent, the safety of a user is protected, the fiber units arranged in the wave shape can conduct uniform buffering at all positions when the shell panel is broken, and the service life of the shell panel is prolonged. The broken panel is prevented from being separated from the composite material layer to impact a user, the fiber units which are arranged in a roundabout mode are convenient and fast to debug, production efficiency is improved, the fiber units are not prone to being pulled out, and using is safer.
本发明公开一种用于汽车安全气囊罩盖的复合材料,包括纤维层和覆盖在纤维层上、下两面的任一面或两面的覆盖层,纤维层包括至少一根纤维单元,纤维单元在纤维层所在面上左右延伸排布或在左右方向迂回排布,纤维单元在左右方向上呈直线排布或呈波浪形排布;复合材料固定于汽车安全气囊的罩盖上。本发明使得复合材料在左右方向具有较强的拉伸强度,安全气囊弹出时,固定在安全气囊壳体面板的复合材料能够较大程度防止壳体面板碎裂,保护使用者的安全,且波浪形排布的纤维单元能够在壳体面板碎裂时在各处进行均匀缓冲,防止碎裂的面板脱离复合材料层对使用者造成冲击,迂回排布的纤维单元调试方便快捷,提高了生产效率,且不易抽出,使用更加安全。
