Patent

CA 2650438

The invention relates to a composite article comprising a metal sheet of at least 0.25 mm thickness and at least two unidirectional sheets, with the metal in the metal sheet having a melting point of at least 350°C, whereby the unidirectional sheets comprise at least 2 mono-layers of unidirectional oriented high performance fibers, with the direction of the said fibers in a mono-layer is at an angle .alpha. to the direction of the fibers in an adjacent mono-layer. The invention furthermore relates to a process for the manufacture of a composite article and the use of the composite article in buildings and constructions, vehicles, and ballistic applications, especially under conditions of heat and fire.

Article composite constitué d'une feuille de métal d'au moins 25 mm d'épaisseur et d'au moins deux feuilles unidirectionnelles, le métal de la feuille de métal ayant un point de fusion d'au moins 350°C. Les feuilles unidirectionnelles comprennent au moins 2 nanocouches de fibres hautes performances orientées unidirectionnellement, le sens desdites fibres dans une monocouche faisant un angle .alpha. par rapport à celui des fibres de la nanocouche adjacente. L'invention concerne également un procédé de fabrication d'un article composite et son utilisation dans le bâtiment, les véhicules et les applications balistiques, en particulier en conditions de chaleur et de feu.
