Title (EN) IMPROVEMENTS IN AND RELATING TO LAYERED FIBRE STRUCTURES
(FR) AMELIORATIONS RELATIVES A DES STRUCTURES DE FIBRES EN COUCHES
Abstract:
(EN) The present invention relates to a fibre structure comprising an assemblage of rigidified or rigidifiable fibres characterised in that said assemblage is provided in at least one surface thereof with a matrix layer of a thermoplastic material which is compatible with said fibres and imparts a substantially continuous surface to said assemblage. In a particular aspect of the present invention a layer of thermoplastic material may be located juxtaposed a shaping surface and the assemblage of fibres capable of shrinking on heating, said shrinkable fibres being clamped about said shaping surface to restrain shrinkage thereof in at least two dimensions and thereafter heating the material whereby the shrinkage forces generated by the fibre assemblage is caused to act against the forming surface thereby to force the fibre structure into the thermoplastic material. The structures in accordance with the present invention have been found to be particularly useful in ducting, tubing conduiting or decorative panels for use in vehicles.
(FR) Structure de fibres comprenant un assemblage de fibres rigidifiées ou pouvant être rigidifiées, caractérisées en ce que ledit assemblage est doté dans au moins une de ses surfaces, d'une couche matricielle en matière thermoplastique, laquelle est compatible avec lesdites fibres et confère une surface sensiblement continue auxdits assemblages. Dans un aspect particulier de l'invention, on peut juxtaposer une couche en matière thermoplastique à une surface de façonnage, l'assemblage de fibres pouvant rétrécir par chauffage, lesdites fibres rétrécissables étant serrées autour de ladite surface de façonnage afin d'en limiter le rétrécissement dans au moins deux dimensions, puis on chauffe la matière de sorte que les forces de rétrécissement produites par l'assemblage de fibres agissent contre la surface de formage, de manière à forcer la structure de fibres à passer dans la matière thermoplastique. On a découvert que les structures de l'invention sont particulièrement utiles dans des conduits, des tubes, des tuyaux ou dans des panneaux décoratifs utilisés dans des véhicules.
