A process for the production of manufactured articles in composite material comprises at least one supply phase of a plurality of layers and at least one coupling phase of the layers. The coupling phase comprises at least one step of arrangement of the layers overlapped onto each other to create at least one stratified body. The coupling phase comprises at least one step of positioning the stratified body inside a mould. The coupling phase comprises at least one firing step of the layers positioned inside the mould. The supply phase comprises at least one supply step of at least one basic layer and at least one supply step of at least one reinforcement layer.

A structural member 10 includes a hat member 1 and a closing plate 2. The length LY of the tubular portion formed by the hat member 1 and the closing plate 2 is 6 or more times the height H of a pair of side walls 11 and 12. Each of the side walls 11 and 12 includes a high-strength portion 11A or 12A and low-strength portions 11B or 12B. The high-strength portion has a yield strength not less than 500 MPa. The low-strength portions have a yield strength of 60 to 85% of that of the high-strength portion. Each high-strength portion extends a distance not less than (⅔)H and not more than 3H as measured in the direction in which the ridges extend, and is provided such that the high-strength portions of the pair of side walls face each other. A pair of low-strength portions sandwich the associated high-strength portion.

Disclosed are a polymer resin composition comprising: a binder resin including an olefin-based polymer resin; a carbon fiber surface-treated with a predetermined compound; and a modified polyolefin resin grafted with polyetheramine-bonded dicarboxylic acid or an acid anhydride thereof, a polymer composite tape including the polymer resin composition, and a front bumper of a vehicle equipped with the polymer composite tape.

An attachment plate and towing lug combination for a vehicle having a crush can and a bumper beam includes a plate and a towing lug. The plate has a central portion and a flange portion. The towing lug is attached to the central portion of the plate and extends from an outer surface of the central portion of the plate. The flange portion of the plate is attachable to an end portion of the crush can. The central portion of the plate is attachable to a first side portion of the bumper beam. The towing lug extends to at least an outer surface of a second side portion of the bumper beam when the flange portion of the plate is attached to the end portion of the crush can and the central portion of the plate is attached to the first side portion of the bumper beam.

A metallic polypropylene resin composition is provided herein. The metallic polypropylene resin composition provides appearance characteristics that are similar to those provided by painting, but without painting. The metallic polypropylene resin composition of the present invention has excellent physical properties such as scratch resistance, and thus may be applied to molding methods, such as a molded in color (MIC) method. The resin composition is useful as a material for automobile interior and exterior parts, as wells as electric and electronic products, which can be molded by the MIC method.

A method of managing collisions, the method comprising: identifying a first crash structure (22) and determining an initial stiffness of the crash structure; determining a level of aggressivity of the collision based on the predicted energy absorption for each vehicle; identifying a first crash structure whose stiffness can be adjusted, and determining a subsequent stiffness value for the crash structure based on the determined amount of energy to be absorbed by each of the vehicles such that the energy absorbed by the crash structure is changed and the level of aggressivity is reduced; and stiffening the first crash structure to the determined stiffness value.

An impact absorption unit provided between an inside member and an outside member that form a vehicle body and configured to absorb an impact may include: a first absorption body which includes composite material and protrudes from an inside surface of the inside member toward the outer member, with an open receiving space formed in the first absorption body; and a second absorption body which includes composite material and protrudes from an inside surface of the outside member toward the inside member such that the second absorption body is inserted into the open receiving space.

An automobile bumper is provided in which the bumper beam includes a middle curved part that curves concavely rearwards and a pair of left and right curved parts that curve convexly rearwards, and the left and right curved parts includes a rear side frame connecting part and a load input part projecting rearwards the most among the bumper beam parts. Since the bumper beam includes a compression-resistant reinforcing part provided along the inner face in the fore-and-aft direction of the load input part, and an extension line of the compression-resistant reinforcing part is directed toward the vicinity of the load input point of the load input part, supporting the compressive load by the compression-resistant reinforcing part to thus prevent the bumper beam from being destroyed enables the strength toward bending deformation to be enhanced without reinforcement by increasing the plate thickness of the bumper beam.
