Abstract

La présente invention concerne les applications de composites a structure fibres et matrices et en particulier celles concernant des structures fortement stressées telles : les pales d'hélicoptères, les ressorts composite de suspension véhicules, les structures d'avion ou de bateau composites, les châssis automobile composite. Lorsque l'homme de l'art souhaite interfacer une fibre de renforcement, par exemple une fibre de verre, avec une matrice organique, par exemple de l'époxy, il utilise des surfactant dont les plus usités sont des « Minichaines mi Organiques mi Minérales » (= MOM) Un inconvénient considérable des MOM actuels et leur très petite taille. Ces surfactants sont extrêmement efficace ; mai, du fait de leur faible dimension et de leur arrangement moléculaire, ils ne peuvent pas s'allonger sous contrainte et donc ils peuvent facilement être brisés si la contrainte locale dépasse leur capacité de contrainte maxi. • Or dans un composite fortement stressé, toutes les fibres ne sont pas soumises aux mêmes efforts. Il y a donc de nombreuses fifres surchargées qui sollicitent, de façon exagérée leur MOM provocant la rupture des dit MOM. • Or dans un composite subissant un fort gradient de contraintes le long des fibres, on peut atteindre, localement, la limite de rupture des dites MOM. La présente invention a pour objet de résoudre ce problème.The present invention relates to the applications of composites with a fiber and matrix structure and in particular those relating to highly stressed structures such as: helicopter blades, composite vehicle suspension springs, composite aircraft or boat structures, automobile chassis. composite. When a person skilled in the art wishes to interface a reinforcing fiber, for example a glass fiber, with an organic matrix, for example epoxy, he uses surfactants, the most widely used of which are "Mini-chains, half Organic, half Mineral. »(= MOM) A considerable drawback of current MOMs and their very small size. These surfactants are extremely effective; May, due to their small size and molecular arrangement, they cannot elongate under stress and therefore they can easily be broken if the local stress exceeds their maximum stress capacity. • However, in a highly stressed composite, all the fibers are not subjected to the same forces. There are thus many overloaded fifes which request, in an exaggerated way their MOM causing the rupture of the said MOM. • However in a composite undergoing a strong gradient of stresses along the fibers, one can reach, locally, the breaking limit of said MOM. The object of the present invention is to solve this problem.
