Title
(EN) STRUCTURAL STRENGTHENING
(FR) RENFORCEMENT STRUCTUREL
Abstract
(EN)
Means for improving the strength of hollow mechanical structures, and especially for improving the impact strength of structural members in motor vehicles. Portions to be strengthened are filled with a rigid non-foamed mass with a specific gravity of preferably between 0.4 and 0.7. This can be cast in position or moulded externally and inserted when solid. The precursor mixture which hardens is pumpable and preferably comprises an epoxy or vinyl ester resin and hardener therefor, glass or plastic hollow micro-spheres, and optionally fibre reinforcement, preferably glass fibres.
(FR)
L'invention concerne des moyens permettant d'améliorer la résistance de structure métallique creuse, et en particulier d'améliorer la résistance aux impacts d'éléments de structure dans des véhicules à moteur. Les parties à renforcer sont remplies d'une masse non-alvéolaire rigide dont le poids volumique est compris de préférence entre 0,4 et 0,7. Cette masse peut être coulée dans les parties à renforcer ou bien elle peut être moulée extérieurement puis insérée une fois solide. Le mélange précurseur qui durçit peut être pompé et comprend de préférence un époxy ou une résine ester vinylique et un agent de durcissement pour l'époxy ou la résine, des microsphères creuses en verre ou en plastique, et éventuellement des fibres de renforcement, de préférence des fibres de verre.
