  • Method for connecting two bodies
    Patent number: 7235145
    Abstract: The invention relates to a method for connecting two bodies according to which a connection means is arranged between connection surfaces of the bodies to be connected. The connection surfaces and the interlying connection means are held adjacent to each other. At least one of the bodies is mechanically stimulated in order to produce friction and frictional heat. The connection means contains at least one cross-linkable polymer or polymerisable and cross-linkable resin which is converted into a thermoplastic material by means of the frictional heat produced, rendering the connection means and the composite of the two bodies considerably more heat-resistant.
