Zusammenfassung: | The invention relates to the technical field of automobile body structure design, in particular to an automobile A-column stiffening beam based on a carbon fiber composite material and a manufacturing method of the automobile A-column stiffening beam. The automobile A column stiffening beam comprises a hollow stiffening beam body made of a carbon fiber composite material, a side wall outer plate and a side wall inner plate, wherein the hollow stiffening beam body is integrally formed through a 3D weaving technology; the side wall outer plate and the side wall inner plate oppositely wrap the hollow reinforcing beam, two overlapped connecting edges are formed between the side wall outer plate and the side wall inner plate, and every two of the hollow reinforcing beam, the side wall outer plate and the side wall inner plate are connected in a co-curing mode. Two gaps formed by the hollow reinforcing beam, the side wall outer plate and the side wall inner plate are filled with fillers made of carbon fiber composi |
