The invention provides an automobile top lining manufacturing method, an automobile top lining and an automobile. The automobile top lining manufacturing method comprises the following steps that S10, a fiber net and a base material composite board are prepared; s20, aerogel thermoplastic resin powder is scattered between two or more layers of fiber nets, and an aerogel thermoplastic composite fiber net is obtained; s30, needling or spunlacing the aerogel composite fiber net to obtain aerogel thermoplastic composite cloth; s40, compounding the aerogel thermoplastic composite cloth with a fabric layer to obtain a fabric composite layer; and S50, the base material composite plate and one side of the aerogel thermoplastic composite cloth of the fabric composite layer are subjected to compression molding through a mold pressing technology, and the automobile roof lining is obtained. According to the manufacturing method of the automobile roof lining, the aerogel is clamped between the fabric layer and the base material composite board, the light weight, sound insulation and heat insulation functions of the aerogel material can be fully played, and the processing technology is simple and easy to implement.

    本发明提供一种汽车顶衬制作方法、汽车顶衬和车辆,汽车顶衬制作方法包括以下步骤:S10、制备纤维网以及基材复合板;S20、在两层或多层所述纤维网之间撒上气凝胶热塑性树脂粉,得到气凝胶热塑性复合纤维网;S30、针刺或水刺所述气凝胶复合纤维网,得到气凝胶热塑性复合布;S40、将所述气凝胶热塑性复合布与面料层复合,得到面料复合层;S50、通过模压工艺将所述基材复合板与所述面料复合层的气凝胶热塑性复合布一侧压制成型,得到汽车顶衬。根据本发明实施例的汽车顶衬的制作方法,通过将气凝胶夹在面料层和基材复合板之间,不仅能够充分发挥气凝胶材料的轻量化、隔音和隔热功能,而且加工工艺简单,易于实现。
