[0002] As pure electric vehicles become more and more mature, lightweighting is increasingly valued and favored by the pure electric vehicle industry due to the limitations of battery structure and performance. Carbon fiber composite materials are increasingly used in electric vehicles due to their light weight and high strength.

[0003] As an important component of the automobile, the anti-collision beam is made of metal. Although the strength meets the standard, the weight exceeds the standard. However, the strength does not meet the standard without exceeding the weight. At the same time, after selecting carbon fiber composite materials, non-net size molding is adopted and CNC trimming is used afterwards. This not only increases the processing cost, but also destroys the continuity of the fiber, resulting in a decrease in its mechanical properties. Summary of the Invention
