The method comprises the following consecutive steps: providing at least one reinforcement layer and at least one matrix sheet made of thermoplastic material; forming a complex with the reinforcement layer and the matrix sheet; and placing the complex in a production tool so that the thermoplastic material impregnates the fibers of the reinforcement layer(s) in order to form a prepreg. The method comprises, in the production tool, the following consecutive steps: heating the complex to a temperature higher than the melting temperature of the thermoplastic material without applying pressure; heating the complex to a temperature higher than the melting temperature of the thermoplastic material while applying a production pressure higher than atmospheric pressure.

An assembly includes a first part made of composite material including a polymer matrix and a second part made of metal. The two parts are assembled by opposite or assembly faces along an interface subjected to shear loads. The first part is made of a composite having continuous reinforcing fibers in a thermoplastic matrix. The second part includes, on its assembly face, a coupling form having a plurality of patterns. Each pattern has a closed contour in a plane parallel to the assembly face of the second part and extends along a direction normal to the assembly face of the second part. A method for making such an assembly is also provided.

The invention relates to a shock absorber () for the bumper () of a vehicle. The inventive absorber comprises: a support (), and strips () which extend forward from the support and which are equipped with a face () that is directed toward the interior of the absorber. In addition, the invention comprises one opening () for each strip, said opening extending opposite the aforementioned face () and opening onto the exterior of the absorber.

A method and system for molding thermoplastic sandwich material to form a deep-drawn article utilizing a unique clamping technique and mechanism are described. The method includes the steps of positioning a blank of thermoplastic sandwich material having a cellular core over a female die having an article-defining cavity defined by inner surfaces of the female die. Then, an inner portion of the blank is forced into the female die along a substantially vertical axis and against the inner surfaces of the female die to obtain deep-drawn material. During the step of forcing at least one outer portion of the blank immediately adjacent the female die is clamped to guide the at least one outer portion of the blank to travel into the article-defining cavity at an acute angle with respect to the vertical axis. Thickness of at least one side wall of the deep-drawn material is substantially the same as thickness of the blank of thermoplastic sandwich material. The deep-drawn material does not significantly stretch or tear during the step of forcing due to the clamping technique and mechanism.

A vehicle subassembly includes a cooling cassette provided with at least one cassette element and a frame provided with at least one frame element which cooperates with the cassette element to fix the cassette to the frame. A thrust force applied to a face of the cassette that faces toward the front when mounted in the vehicle causes the cassette element to separate from the frame element.

A molding method and an impact resistant automotive part such as a bumper beam resulting from the molding method are obtained wherein a thermoplastic reinforced fiber structure at least partially forms a pair of attachment portions of the part and continuously extends between the attachment portions to link the attachment portions. The method includes the steps of providing a plurality of blanks, heating the plurality of blanks, and stacking the plurality of blanks to form a stack of blanks. The stack is then stamped to form the part including the pair of attachment portions spaced a predetermined distance apart. The thermoplastic reinforced fiber structure has tows of fibers wetted by a resin material such as polypropylene. Preferably, the fibers are woven glass fibers.

A vehicle hood includes a wall, connecting devices for mounting the hood on a vehicle chassis fixed to the wall nearer a rear edge of the wall than to its other edges, and a locking member fixed to the wall for locking the hood to the chassis in a closed position. The locking member is nearer the rear edge of the wall than a front edge of the wall opposite the rear edge.

The inventive combination comprises a front bumper skin ( ) pertaining to a motor vehicle and an inner closing part ( ) pertaining to an engine compartment, mounted to the rear of said skin in relation to the principal direction in which the vehicle travels. The closing part ( ) comprises a front transversal profiled section ( ).
