Abrégé
(EN)
The present invention refers to a new multilayered material, reinforced with fibres and having an improved adhesion between the layers throughout its entire structure; to a process for its preparation and to the articles made with such material, intended to be exposed to adverse conditions, such as strong winds, stretching, temperature changes, such as for example sails for boat.
(FR)
La présente invention concerne un nouveau matériau multicouche, renforcé de fibres et ayant une adhésion améliorée entre les couches à travers sa structure entière ; un procédé pour sa préparation et les articles fabriqués à partir d’un tel matériau, visant à être exposés à des conditions défavorables, telles que des vents forts, l’étirage, les changements de température, tels que par exemple les voiles pour bateau.
