Abstract
A method of fabricating complex frames, e.g. for engines and aircraft comprises forming the principal components of the frame from resin-bonded filamentary material and securing them together, each of the principal components being formed by a method which includes the step of winding the filamentary material about a former having longitudinal axis and impregnating the material with a hardenable resin. One or more of the components so made may form part of the former for one or more of the other components. The method of forming the individual components may further include the step of axially dividing the element which is made by winding filamentary material about a former and impregnating the material with hardenable resin.
