Abstract (en)
[origin: WO9204177A1] The invention relates to a connection node for tubes whose materials are similar and which gives, in addition to lightness, a same expansion coefficient, which is not the case at the present time. The node is comprised of continuous filaments impregnated with resin, forming a hank which is introduced in the mould, and a torsion and a prestressed are applied to the yarns during stoving. The mould is an integral part of the node in order to increase its torsion qualities. Nodes for parabolic structure, platform framework for satellite are examples of numerous industrial applications.
Abstract (fr)
L'invention concerne un noeud de raccordement pour tubes dont les matériaux sont identiques et qui apporte avec la légèreté, un même coefficient de dilatation ce qui n'est pas le cas actuellement. Le noeud est constitué de filaments continus imprégnés de résine, formant un écheveau qu'on introduit dans le moule, on imprime une torsion et une précontrainte sur les fils maintenus pendant l'étuvage. Le moule est partie intégrante du noeud pour augmenter ses qualités à la torsion. Noeuds de structure parabolique, d'ossature de plate-forme pour satellite font partie des nombreuses applications industrielles.
