A component having a flat reinforcing element of a first stiffness and a flat material of a second stiffness. The first stiffness is higher than the second stiffness. The flat reinforcing element has a first end on a first narrow side. The flat material, on a second narrow side thereof, has a second end that bifurcates into two strips. The two strips of the second end enclose the first end on both sides in a zone of enclosure.

Edge design of a flat stiffening structure for a component

The invention relates to a method for producing plastics containers from thermoplastics with inserts which, by exploiting the heat of plasticization, are connected during shaping of the plastics container by a material bond and/or interlocking connection to the container wall, wherein the method provides the use of at least one opening on the insert, which opening forms a melt duct or melt inlet and/or melt passage for plasticized or plastic material of the container wall, wherein the method is distinguished in that the opening is monitored as a reference opening by optical and/or sensory means during the production of the connection, wherein the degree of penetration of the opening with thermoplastic from the container wall is used as a measure of the quality of the connection.

The invention relates to an extrusion-blow-molded fuel tank () of thermoplastic material comprising a tank wall of a composite of various layers obtained in various production operations, at least one first layer comprising at least one shell-shaped supporting shell () and a second layer of a thermoplastic material forming an adhesive bond with the supporting shell (), and the supporting shell () having a greater strength than the second layer. The supporting shell () forms an inner layer of the tank and the second layer forms an outer skin of the tank, two supporting shells within the tank forming a supporting cage or a supporting housing.

The invention relates to a fuel tank for a motor vehicle, which is made up of two shells which are complementary to one another, wherein the shells are supported against one another by at least one strut penetrating the tank (), connecting opposing wall regions of the tank. The strut is configured as a two-part hollow strut (), wherein the parts of the hollow strut are latched together via a plug connection and the latching connection is secured by at least one closure body () at least partially filling up the cross section of the hollow strut () at least level with the latching connection.

Tank for a motor vehicle, in particular fuel or auxiliary fluid tank for a motor vehicle, and method for producing such a tank

The invention concerns a process for the production of hollow bodies of thermoplastic material, in particular a process for the production of fuel tanks of plastic material. In the process according to the invention preforms in web or band form of plasticized plastic material are shaped in a multi-part tool forming a mold cavity by expansion of the preforms and causing them to bear against the internal contour of the mold cavity. The process firstly includes the production of two mutually complementary intermediate products in the form of shell portions. Then respective built-in fitment components are secured to the respective insides of the shell portions, which face towards each other in the installation position, wherein at least some built-in fitment components of mutually complementary shell portions are respectively of mutually complementary configuration, in the sense that they can be joined to provide an assembled component or to provide a functional unit. The shell portions are assembled in such a way that the mutually complementary built-in fitment components engage into each other and/or come into operative connecting relationship with each other.
