A connection between composites (10, 12) with non-compatible properties and a method of preparing of such connections are provided. The composites comprise first and second type fibres, respectively, as well as resin. The connection comprises a transition zone (52) between the composites (10, 12) having a layered structure. The transition zone may optionally comprise a transition member and the transition member may optionally be integrated with one or more of the composites. Examples of non-compatible properties where the present connection will be appreciated are great differences in stiffness, e.g. Young's modulus, or in coefficient of thermal expansion.
Cette invention se rapporte à une connexion entre des composites (10, 12) ayant des propriétés non compatibles, et à un procédé de préparation de telles connexions. Ces composites comprennent un premier et un second type de fibres, respectivement, ainsi que de la résine. La connexion comporte une zone de transition (52) entre les composites (10, 12) ayant une structure en couches. La zone de transition peut éventuellement contenir un élément de transition, lequel peut éventuellement être intégré dans un ou plusieurs des composites. Les exemples de propriétés non compatibles pour lesquels cette connexion serait appréciée sont une grande différence de rigidité, par exemple du module de Young, ou une grande différence de coefficient d'expansion thermique.
