The invention relates to a square tapered aluminum alloy automobile front carling based on an embedded carbon fiber. The square tapered aluminum alloy automobile front carling based on the embedded carbon fiber is characterized in that the section of the front carling is composed of two parts, namely the aluminum alloy outer wall and a carbon fiber reinforced plate. An aluminum alloy outer plate is little in elasticity modulus and good in deformation mode and the carbon fiber reinforced plate has the strong collision energy absorption capability. By means of the two new materials are combined and a square tapered structure, the contradiction among the high energy-absorption performance, the low-collision-acceleration peak value and the good crushing mode can be coordinated in a satisfying manner in the collision safety design process. The square tapered aluminum alloy automobile front carling based on the embedded carbon fiber has great significance in improvement of the collision performance and weight reduction.
