A method and an apparatus for the production of continuous composite materials from unidirectional reinforcing fibers and from thermoplastics, the longitudinally moved bundle of parallel continuous reinforcing fibers being preheated and impregnated with a continuously supplied thermoplastic melt, whereupon the continuous composite material thus formed is cooled. In order to improve the impregnating operation, it is proposed, according to the invention, that the thermoplastic melt form an elongate impregnation stage, into which mechanical energy is introduced continuously in order to reduce the melt viscosity, and that the preheated fiber bundle be drawn continuously through the zone of reduced melt viscosity.

Method and apparatus for the production of continuous composite materials

The invention relates to an orthopaedic clamped connection as a functional element for force transmission in a prosthesis, comprising a tube socket and a tube made of light metal. To increase the dynamic stressability, the contact area between tube socket and tube made of light metal is provided with an intermediate layer which is composed of a low molecular weight carrier material in which at least one lubricant and/or auxiliary is embedded.
