The invention consists in a composite part, such as a divertor plate for the “first wall” of a fusion reactor, adapted to endure a high thermal load, which is made, at least in some sections, of tungsten or a tungsten alloy. In accordance with the invention, the sections are not constructed massively from tungsten or a tungsten alloy, but rather are made as a laminated packet (multi-layeredness packages), with other enhanced alloys as copper, lanthanum alloy etc, in order to improve the susceptibility to fissures. This invention, heat shield is produced either as a massive block-shaped heat sink or as an actively cooled heat sink. This technology can find other suitable in other harsh environment such as Nuclear, Furnaces, Heat treatments and Materials. It can be also applied for high performances cooling systems in big science applications.
