Characteristics of the titanium fibre mesh The porous titanium fibre structures that we use for medical applications are fabricated by interengaging and intertwining a multiplicity of titanium fibres. After compression the fibre structures are sintered at high temperature to bond the fibres at their points of contact. The resulting titanium mesh has a porosity of about 85% and a weight of 600g/m2. The average fibre diameter of the titanium mesh is 50μm, while the mean poresize of the mesh is 250μm. Due to a special production process, in which the fibres are scraped from a roll of titanium foil, the fibres have a rectangular cross section. Consequently the potential contact surface of the intermingled fibres is larger than it would be in case of a circular shape. Scanning electron microscopic examination reveales that the surface of the titanium fibres was not smooth. Irregular, rather profound, longitudinal grooves appeare to be present on the surface of the fibre. Three scanning electron micrographs of the fibre mesh with different magnifications are presented below.
