An aramid composite material according to the present invention is structured such that an aramid fabric prepreg (1), an aramid fabric laminate (2), a unidirectional raw fabric (3), an aramid fabric laminate (4), and an aramid fabric prepreg (5) are successively laminated. The present invention comprises an aramid composite material configured such that additional unidirectional raw fabrics (6, 9) and aramid fabric laminates (7, 8) are repeatedly laminated alternately at least once between the aramid fabric laminate (2) and the unidirectional raw fabric (3) and/or between the unidirectional raw fabric (3) and the aramid fabric laminate (4), thereby positioning the unidirectional raw fabrics (6, 9) between two aramid fabric laminates. An aramid composite material and a helmet manufactured using the same, according to the present invention, are not only lightweight but absorb shocks efficiently during bullet impacts, thereby providing excellent bullet-proofing property, and can minimize deformation of the rear surface during bullet impacts. |
