Provided are an energy-absorbing member and a method for producing same, the energy-absorbing member having a structure in which a plurality of fiber reinforced resin layers are layered in the thickness direction of the member, the energy-absorbing member including, as the plurality of fiber reinforced resin layers, at least a plurality of unidirectional materials each comprising unidirectionally aligned reinforcing fibers and a resin and a plurality of cross materials each comprising a reinforcing fiber woven fabric and a resin, wherein the energy-absorbing member is characterized in that the lengths of the plurality of unidirectional materials in an external-loading direction are changed sequentially. The optimum energy absorption quantity can be easily adjusted and set in accordance with a target value without greatly changing the outward shape of the member. |
