Polyamid PA6 woven and non-woven fabrics are commercially coated by Statex Bremen with copper or silver-copper layers in thicknesses of few microns. Using specific thermal treatments the textile’s polymer can be removed and the metal layers be sintered, leading to purely metallic textile structures which consist of hollow metal fibres. Compressed multilayers of such textiles can be sintered to obtain porous metal blocks. Furthermore, the textiles can be combined with massive components like round and flat tubes or foils during the sintering process. Measurements of the thermal conductivity of sintered blocks showed a very good conductivity in the lateral direction of the fabric layers but also good conductivity in transverse direction. Latter fact is due to the hollow character of the fibres which leads to local deformations at contact points to neighboring fibres and better sintering contacts. Graded structures with strongly an-isotropic thermal conductivities can be produced. The sintered structures exhibit very high weight specific surfaces. The main application fields can be seen in thermal components for which a high porosity, a high surface-to-volume ratio and a good thermal conductivity is required. Typical examples are evaporators or supports for thermally active materials adsorbents (e.g. zeolites or metal-organic frameworks MOF) or phase-changing materials PCM. Further potential applications can be found in chemical installations, e.g. for the evaporation or condensation of specific chemicals.
