Title
(EN) LAMINATE
(FR) STRATIFIE
Abstract
(EN)
A laminate for lining a passage, which is entirely or partially surrounded by walls, above or under the ground, which laminate comprises at least one layer of a reinforcement (4) of continuous fibre, a curable resin (5) and a plastic sheet or plastic film (3) which is on the inside of the laminate when the laminate is inserted into the passage (10) which shall be lined. In order to give such laminates corrosion durability and flexibility which stand on a par with the strength of the laminate so that not anyone of these parameters will determine the life length of the lining, there is arranged a mat (8) of fibres between the inner film (3) and the reinforcement (4) which mat on its side which is turned to the inner film (3) has cut fibres (13), and which together with its cut fibres can absorb resin for concentration of curable resin to the inner surface of the cured laminate.
(FR)
Stratifié servant à revêtir un passage entièrement ou partiellement entouré par des parois et situé au-dessus ou au-dessous du sol; ledit stratifié comprend au moins une couche de renforcement (4) en fibres continues, une résine durcissable (5) et une feuille ou une pellicule en plastique (3) se trouvant à l'intérieur du stratifié quand il est introduit dans le passage (10) à revêtir. Pour rendre ledit stratifié résistant à la corrosion et souple, mais également résistant, afin que l'ensemble de ces paramètres soit déterminant pour sa durée de vie, on dispose un revêtement de fibres (8) entre la pellicule intérieure (3) et le renforcement (4), dont la face tournée vers ladite pellicule intérieure (3) possède des fibres coupées (13) pouvant absorber la résine pour qu'elle se concentre sous forme durcie sur la surface intérieure du laminé.
