The invention relates to a natural bamboo fiber composite material automobile interior trim part based on a sandwich structure and a preparation method, and belongs to the field of automobile interior trim parts. The automobile interior trim part is composed of an interior trim plate and a decorative layer laid on the surface of the interior trim plate, the interior trim plate is of a sandwich structure and is composed of a glued natural bamboo fiber composite felt, artificial fiber prepreg cloth and another glued natural bamboo fiber composite felt, and the three layers of materials are bonded together through high-temperature mold pressing. The preparation method mainly comprises a sizing bamboo fiber composite felt manufacturing process, an artificial fiber prepreg cloth manufacturing process and a sandwich structure mold pressing process, and finally, a mold pressing material is subjected to facing. According to the invention, the bamboo fibers are introduced into the automotive upholstery, through sandwich structure combination, the high-strength characteristic of the composite material layer can be maintained, the overall structural strength of the molded automotive upholstery is ensured, and the green development of the composite material is facilitated. In addition, the natural bamboo fibers are of a hollow structure, VOC released by the internal space of the automobile can be absorbed in a larger area, and the smell of the automobile is reduced.

    本发明涉及一种基于夹层结构的竹原纤维复合材料汽车内饰件及制备方法,属于汽车内饰件领域。该汽车内饰件由内饰板和铺设在其表面的装饰层构成,内饰板具有夹层结构,由施胶竹原纤维复合毡、人工纤维预浸布和施胶竹原纤维复合毡三层材料构成,通过高温模压粘合在一起。其制备方法主要包含:施胶竹原纤维复合毡制造工序、人工纤维预浸布制造工序和夹层结构模压工序,最后对模压材料进行饰面。本发明将竹原纤维引入汽车内饰件,通过夹层结构组合,可以保持复合材料层的高强度特性,保证成型后汽车内饰件整体的结构强度,有助于复合材料的绿色化发展。此外,竹原纤维具有中空结构,可以实现更大面积地吸收汽车内部空间释放的VOC,减小汽车的气味。
