Abstract
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.
