Abstract
(EN)
The present invention is an improved composite clamp having a greatly reduced profile, eliminating most of the block portion of the prior art clamp to substantially reduce the weight. The composite clamp of the present invention can be appropriately described as a composite strap clamp. The clamping sections are molded in an arcuate shape without the presence of block material. To provide high strength, reinforcing fibers comprising structural woven carbon fiber cloth are used together with a thermoplastic, thermoset, or thermosettable polymer. Continuous reinforcing fibers extend longitudinally through the clamping sections to provide high strength and low delamination.

La présente invention concerne un collier composite amélioré ayant un profilé grandement réduit, éliminant la majorité de la partie par blocs du collier de l'art antérieur afin de réduire substantiellement le poids. Le collier composite selon la présente invention peut être décrit de manière appropriée comme un collier d'attache composite. Les sections du collier sont moulées en une forme arquée sans la présence de matériau par blocs. Afin de fournir une résistance élevée, des fibres de renforcement comprenant des toiles de fibres de carbone tissées structurelles sont utilisées conjointement à un polymère thermoplastique, thermodurci, ou thermodurcissable. Des fibres de renforcement continues s'étendent longitudinalement le long des sections du collier afin de fournir une résistance élevée et une faible délamination.
