A bumper for vehicle may include an injection-molded bumper cover; and a reinforcing structure provided in a linear shape with fiber reinforced composite material and coupled by direct fitting onto a rear surface of the bumper cover to reinforce a rear side of the bumper cover.

A front bumper system of a vehicle includes a bumper beam disposed on a front end of the vehicle, and the bumper beam has a plurality of openings which are open toward a cooling module disposed within a front compartment of the vehicle. The bumper beam has a plurality of ribs by which the plurality of openings are defined, and each rib has a streamlined cross-section whose thickness gradually decreases from the front of the vehicle toward the rear of the vehicle.

Apparatus and methods for additively manufactured structures with augmented energy absorption properties are presented herein. Three dimensional (3D) additive manufacturing structures may be constructed with spatially dependent features to create crash components. When used in the construction of a transport vehicle, the crash components with spatially dependent additively manufactured features may enhance and augment crash energy absorption. This in turn absorbs and re-distributes more crash energy away from the vehicle's occupant(s), thereby improving the occupants' safety.

In a crash box, a first extending portion extends from a front end of a first body upper portion in a vehicle front-rear direction of a first body portion, and a second extending portion extends from a front end of a second body lower portion in a vehicle front-rear direction of a second body portion. When an impact load is transmitted to the front ends of the first body portion and the second body portion in the vehicle front-rear direction, a rotation moment toward the lower side of the vehicle acts on the first extending portion and a rotation moment toward the upper side of the vehicle acts on the second extending portion. This can suppress peeling between first and second left side bonded portions and between first and second right side bonded portions of the first body portion and the second body portion.

An impact absorbing structure for a vehicle according to the present invention includes: a resin frame member extending in a vehicle front-rear direction and having an opening portion in a surface thereof on one side in a vehicle width direction; and a strut member disposed in the opening portion of the frame member. The frame member includes a frame body having the opening portion, and a rib protruding at least either upward or downward from the frame body and extending in the vehicle front-rear direction. The strut member is disposed between a pair of opening edges for defining an upper edge and a lower edge of the opening portion and at a position abuttable against the paired opening edges, when the frame member is deformed by input of a load at a time of oblique collision from upward or oblique collision from downward.

A structural component for a motor vehicle is provided. The structural component includes a closed hollow profile including fiber composite material, with a profile outer casing surrounding a profile volume. The structural component also includes at least one reinforcing bulkhead which is arranged in the profile volume on at least one section of an inner casing surface of the profile outer casing. The height of the at least one reinforcing bulkhead, perpendicularly from the inner casing surface, in at least one position in which the at least one reinforcing bulkhead is arranged on the inner casing surface, is lower than a passage height of the profile volume in this position.

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 method to prepare a composite laminate object containing an extrusion grade 7xxx Al substrate and a fiber-reinforced polypropylene layer adhesively laminated to the substrate; is provided. The process includes shaping and cutting an extruded 7xxx aluminum to a profile, assembling a layered arrangement of the 7xxx Al profile as substrate, an adhesive film and a fiber reinforced polypropylene preform, heating the layered arrangement to a temperature of 160-175 C. to melt the polypropylene and activate the adhesive film, applying pressure to at least a surface of the fiber reinforced polypropylene preform to mold the preform to the shape of the extruded 7xxxAl substrate and obtain a semi-finished laminate object, cooling the semi-finished laminate object to 90 C., optionally, cooling the semi-finished laminate object to room temperature for inventory storage; heat treating the semi-finished laminate object at 90 C. for 2 to 8 hours; and then heat treating the semi-finished laminate object at 130 C. to 150 C. for 8 to 16 hours; and cooling the heat treated object to obtain the composite laminate object.

A structural component, in particular for a vehicle, includes a beam and at least one energy absorption device which is disposed on a portion of the outer surface of the beam. The beam is profiled and has at least one inner chamber.

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.
