Abstract
The composite laminate is made of two metal parts 1, 2 and a pair of thermal insulating bars of fiber reinforced synthetic material. Each metal part has a longitudinally extending groove which is provided with two rows of transversely disposed teeth which cut into the flanks of anchoring strips on the synthetic bars during pressing in of the strips in the respective grooves. The pressing in of the synthetic material into the teeth of the harder metal parts forms a strong bonded connection which resists the stresses imposed upon the laminate during use. Deformable tabs on the metal parts are used to ensure locking of the synthetic bars in place. The space required for production of the laminate is reduced essentially to the length of the metal parts.
