The invention discloses a carbon fiber fabric composite material whole vehicle framework which is made of a three-dimensional framework prepared by annularly connecting carbon fiber fabric composite material honeycomb tubes supported by a carbon fiber fabric composite material, the inner supports of the honeycomb tubes are star-shaped supports, annular supporting frames are arranged in honeycomb holes of the star-shaped supports in the honeycomb tubes, and the annular supporting frames are connected with the honeycomb tubes. The annular supporting frame is composed of a winding pipe or a braided pipe. The honeycomb-shaped supported tubular structural part made of the carbon fiber fabric composite material and the connector are connected in an inserted mode to form the whole vehicle framework, so that when the vehicle framework is stressed, borne force can be distributed on all honeycomb-shaped branches and evenly distributed on the structural part, and the overall stress degree of the structural part is enhanced; compared with a solid structural member, the material and the weight are reduced, the cost is saved, and meanwhile, compared with a hollow structural member, the stress capacity is higher.

    本发明公开了一种碳纤维织物复合材料整车骨架,是由碳纤维织物复合材料支撑的碳纤维织物复合材料蜂窝管环接制备而成的立体框架制成,所述蜂窝管的管内支撑为星状支撑,所述蜂窝管内的星状支撑的蜂窝孔内为环状支撑架,所述环状支撑架由缠绕管或者编织管构成。本发明将碳纤维织物复合材料制成的蜂窝状支撑的管状结构件和接头插接形成整车骨架,可以使车骨架在受力时,将所承受的力分布于蜂窝状的各个支路,均匀分布于结构件上,增强了结构件整体的受力程度,本发明将结构件支撑蜂窝状,较实心结构件减少了材料和重量,节约了成本,同时相较于空心结构件具有更强的受力能力。
