[0042] The door outer panel assembly 1 uses an 8-layer carbon fiber structure, which is composed of a first twill fabric layer, a first unidirectional prepreg layer, a second twill fabric layer, a second unidirectional prepreg layer, a third unidirectional prepreg layer, a third twill fabric layer, a fourth unidirectional prepreg layer, and a fourth twill fabric layer.

[0048] The 21-layer carbon fiber structure of the door inner panel assembly 2 can be partially thinned and partially thickened to meet the installation requirements of door accessories on the inner panel. The door inner panel assembly 2 with this structure increases the strength of the vehicle body while improving the quietness of the door interior and exterior panels.
