ABSTRACT:
Shaped structures containing polytetrafluoroethylene are connected with themselves or with another material stable up to 400.degree.C under elevated pressure and temperature using as interlayer between the surfaces to be connected at least one copolymer of tetrafluoroethylene and perfluoroalkyl-perfluorovinyl units in a determined proportion. The composites obtained have a high mechanic strength and the joint has good temperature endurance properties.
