    摘要: The core/casing-fibre consists of plastic such as polypropylene, polyethylene or a mixture of these raw materials or other thermoplastic polymers. The fibre diameter is 0.15 to 2.0 mm and the core/casing-fibre in a continuous or intermittent manner has a structured surface. This is produced by an embossing (5) which designed in a single-sided or multi-sided manner, and its depth is at least 10% of the average fibre diameter. The embossing (5) may be designed in a transverse or diagonal manner or in another shape to the fibre course, but in any case is incorporated after a stretching of the fibre by the factor 5 to 15. The core/casing-fibre is cut in section of 10 to 80 mm and grouped together into bundles of several thousand and wrapped in a water-soluble plastic film. Such fibres are used for increasing the tensile strength, for improving the post-failure behaviour or generally for the mechanical reinforcement in cement-bonded building materials, in particular concrete. The bundles may be worked into the building material together with the plastic film without any disadvantages.

    摘要: Method for making plastic fiber for application in concrete with largest grain diameters >4 mm, with an average diameter of 0.15 to 2 mm, corresponding to approximately 160 to 28,000 dtex. Using a co-extrusion process, a bi-component fiber is formed having a central core and a casing around the central core, the central core and the casing contain different pure polymers or polymer mixtures, and then the co-extruded bi-component fiber is stretched by a factor of 5 to 15, and thereafter a structured or grooved surface is embossed onto the co-extruded stretched bi-component fiber. The embossing is performed such that a depth of the embossing is more than 10% of an average fiber diameter, and a maximal distances of structure tips within incorporated structures of the embossing in an axial direction lie in a region between 0.5 mm and 3 mm.
