The integral type front-end module includes a frame having an upper member, a lower member, and a pair of vertical members that connect the upper and lower members. The integral type front-end module also includes a horizontal back beam that connects the vertical members, a first vertical back beam that connects middle portions of the upper member and the lower member, and a pair of second vertical back beams, each disposed between one of the vertical members and the first vertical back beams. In particular, the horizontal back beam, the first vertical back beam, and the second vertical back beams are formed integrally.

A back beam for a vehicle having a charge and discharge function utilizing carbon fiber used as a reinforcing material in a back beam of a vehicle, may include a reinforced negative electrode portion formed of carbon fiber and formed to extend in the width direction of the vehicle, a positive electrode portion disposed opposite to at least a portion of the reinforced negative electrode portion, a solid electrolyte portion disposed between the reinforced negative electrode portion and the positive electrode portion to be in contact with the reinforced negative electrode portion and the positive electrode portion, and a molding portion formed of resin and surrounding the reinforced negative electrode portion, the positive electrode portion and the solid electrolyte portion.

A bumper beam for a vehicle is attached to a front or rear portion of the vehicle, includes a beam main body having a front surface opposite to a surface to be attached to the vehicle, the front surface being curved outwardly, and the beam main body having a C-shaped section opened outwardly toward the front surface, and stay portions formed on both sides of the beam main body, each of the stay portions having an opening at a rear surface thereof. The beam main body includes a fiber reinforced plastic.

A unit of a combined front bumper beam and front end module (CFF unit) is provided with a configuration in which an impact energy absorbing space formed is as a closed space and a chassis component mounting space is formed as an open space. The impact energy absorbing space and the chassis component mounting space are formed as an integrally formed structure. This structure is divided into a bumper back beam to which impact energy is transmitted, a crash box molded integrally with the bumper back beam to form the impact energy absorbing spaces at both sides of the bumper back beam, respectively, and a front end module carrier (FEM carrier) molded integrally with the crash box to form the chassis component mounting space at the inward side of the crash box. The bumper back beam, the crash box and the FEM carrier form the CFF unit.
