Beschreibung
Zusammenfassung:	A control rod (23, 24, 25, 46, 100, 120, 136, 152, 168) for incorporation into a composite assembly (40) with at least a first composite preform (10), a second composite preform (13), and a cured resin includes a shaft (50, 105, 128, 174) defining an axis, wherein the shaft is disposable within an aperture (36, 44) in the composite assembly, and a plurality of threads (28) disposed on at least a portion of the shaft. The shaft is made from, among other materials, a thermoplastic material. The threads define a thread pitch that encompasses more than one individual fiber layer forming at least one of the first composite layer and the second composite layer. L'invention concerne une tige de commande (23, 24, 25, 46, 100, 120, 136, 152, 168) destinée à être incorporée dans un ensemble composite (40) comprenant au moins une première préforme composite (10), une seconde préforme composite (13); et une résine durcie comprenant un arbre (50, 105, 128, 174) définissant un axe et pouvant être disposé à l'intérieur d'une ouverture (36, 44) ménagée dans l'ensemble composite; et une pluralité de filets (28) disposés sur au moins une partie de l'arbre. L'arbre est composé, entre autres matériaux, d'un matériau thermoplastique. Les filets définissent un pas de filetage qui englobe plusieurs couches de fibres individuelles formant la première couche composite et/ou la seconde couche composite.
