    摘要: The invention relates to a method of connecting two fuselage sections (1, 2, 21, 22) formed by a fiber-reinforced plastics material, in particular wound fuselage sections (1, 2, 21, 22) for aircraft fuselage cells, having a multiplicity of stringers (10, 11, 35, 36) arranged with a uniform distribution at a distance from and parallel to one another on the inner side of an outer skin (3, 4, 25, 26), with the formation of a transverse joint (5, 30). In order to be able in particular to join together wound CFRP fuselage sections so that simple tolerance compensation is made possible in a continuous, industrial production process, the method according to the invention comprises the following steps: aligning a first and a second fuselage section (1, 2, 21, 22) with respect to one another, heating and adapting at least one transverse butt strap (9, 23), formed by a fiber-reinforced thermoplastic material, in such a way that tolerance compensation between differing cross-sectional geometries of the first and second fuselage sections (1, 2, 21, 22) is made possible, or heating at least one end region (27) of a second fuselage section (2, 22) formed by a fiber-reinforced thermoplastic material, and joining together the two fuselage sections (1, 2, 21, 22).

    摘要: The invention relates to a process for the simultaneous preconcentration and preselection of at least one group of used polymer materials of various compositions, as a mixture with one another and with contaminant materials, originating from the destruction, by grinding, of durable consumer goods that have reached the end of life, which can be recycled in the fields of plastics processing. This process is characterized in that it includes, in order, a) a step of separation in a hydraulic medium, the density of which is adjusted to a value ds between 1.100 and 1.900, b) a step of separation of the supernatant fraction from a), a step of grinding c) the supernatant fraction from b), then a step d) of mechanical separation of the fraction originating from c) followed by a wetting step e) and a final step f) delivering preconcentrated and preselected used synthetic polymer materials.
