A process for the production of a tubular semi-finished product from a composite tube of thermoplastic matrix fibers and temperature-stable continuous reinforcing fibers and a tubular semi-finished product

摘要

Method for producing a tubular semifinished product (1) from a composite tube (2) made of thermoplastic matrix fibers (2a) and thermally stable continuous reinforcing fibers (2b), comprising the following steps: - providing an unconsolidated composite tube (2) made of thermoplastic matrix fibers (2a) and temperature-stable endless reinforcing fibers (2b), - heating a segment (3) of the composite hose (2), - consolidation of the segment (3) by pressing the composite hose (2) in the region of the segment (3 ), - separating the segment (3) into a first sub-segment (3a) and into a second sub-segment (3b), - heating a further segment (4) of the composite tube (2), the two segments (3, 4) Having a defined distance (x) to each other, - consolidating the other segment (4) by pressing the composite hose (2) in the region of the other segment (4), - separating the further segment (4) in a further it first sub-segment (4a) and in a further second sub-segment (4b), so that the resulting semi-finished product (1) at its one end (5) by a first consolidated sub-segment (3a, 4a) and at its other end (6) a second consolidated sub-segment (3b, 4b) is formed with an unconsolidated composite tube section (7) located between the sub-segments (3a, 4a, 3b, 4b).
