The invention discloses a GFRP/paper honeycomb composite material and a preparation method thereof. The glass fiber reinforced plastic/paper honeycomb composite material is of a layered structure and comprises a top fiber reinforced outer layer, a middle honeycomb layer and a bottom fiber reinforced outer layer, and the fiber reinforced outer layer and honeycomb holes in the honeycomb layer form a closed structure. The product disclosed by the invention is obtained by coating corrugated paper with adhesive tapes, bonding, manually cutting into strips, stretching and forming, drying after stretching, then manually laying the obtained paper honeycomb and the glass fiber mat, spraying polyurethane on the surface, and heating and pressurizing in mould pressing equipment. According to the glass fiber reinforced plastic/paper honeycomb composite material, the weight of an automobile can be reduced, and the method is an effective method for reducing fuel consumption and gas emission.
本发明公开了一种GFRP/纸蜂窝复合材料及其制备方法。本发明的玻璃纤维增强塑料/纸蜂窝复合材料,为层状结构,其包括顶层的纤维增强外层、中部的蜂窝层和底层的纤维增强外层,所述纤维增强外层与蜂窝层中的蜂窝孔形成封闭结构。本申请中的产品是将瓦楞纸涂刷上胶条后,进行粘接、人工切条并拉伸成型,拉伸完成后并进行烘干,随后将得到的纸蜂窝与玻璃纤维毡进行人工铺叠,并于表面喷涂聚氨酯后,放入模压设备中加热、加压得到的。本申请中的玻璃纤维增强塑料/纸蜂窝复合材料,可减轻汽车重量,是一种减少燃料消耗和气体排放的有效方法。
