Definitions

  • a number of methods are known for chemically modifying reinforcing fibers for the production of fiber composite materials in such a way that an improvement in the adhesion between fiber and matrix materials is achieved.
  • the adhesion of the components to one another is essential for many usage properties of composite materials.
  • ILS interlaminar shear strength
  • the carbon fibers can come from various starting materials, e.g. from cellulose derivatives, special pitch types, for example bitumen or polyacrylonitrile.
  • the invention therefore relates to carbon threads, fibers or flat structures with an electrolessly applied metal layer.
  • Preferred metals are nickel, cobalt, copper, gold or silver or alloys of these metals with one another or with iron.
  • the thickness of the metal layer is between 0.05 and 10 ⁇ m, preferably 0.1 - 1 ⁇ m.
  • Preferred carbon fibers have a carbon content> 80% by weight. Fibers with a graphite-like structure and an elastic modulus> 300,000 MPa are particularly preferred.
  • Particularly preferred metals are cobalt and nickel or cobalt-nickel, cobalt-iron, nickel-iron and cobalt-nickel-iron alloys.
  • the invention further relates to composite materials made of electrolessly metallized carbon fibers with polymer matrices, which are characterized by improved fiber-matrix adhesion.
  • Preferred embodiments of these composite materials contain the carbon fibers marked as preferred.
  • the metal layer deposited on the fibers is firmly connected to the substrate.
  • the metallization produces electrically conductive substrates. Depending on the thickness of the metal layer, this can provide protection from electrostatic charge up to lightning protection. When using metals such as nickel or cobalt, shielding from electromagnetic radiation is obtained.
  • the improvement of the ILS is achieved with plastics from different starting points.
  • the metallized carbon fibers according to the invention e.g. the polymer classes listed below: epoxy resins, polyester resins, phenolic resins, aminoplasts, polyurethane resins, silicone resins, polyamides, polyimides, thermoplastic polyesters, polycarbonates and polyacrylates.
  • the reinforcing materials can be used in the form of fibers, fabrics, knitted fabrics or braids.
  • the metallization can be carried out both on the fibers and on the textile fabrics produced therefrom.
  • the metallization can be carried out according to the method described in DE-PS 2 743 768.
  • the activation is preferably carried out by a method which is characterized in that the surface to be metallized is wetted with an organometallic compound of elements of the 1st and 8th subgroups of the Periodic Table of the Elements which is homogeneously distributed in an organic solvent, the organic solvent is removed and the organometallic compound adhering to the surface to be metallized is reduced.
  • the metallization is then carried out approximately as in DE-PS 2 743 768.
  • a carbon filament yarn is activated for 10 seconds in a solution of 0.01 g butadiene palladium chloride, dried and then for 5 minutes in a metallization bath containing 30 g / 1 nickel chloride 6 H 2 O, 10 g / 1 citric acid and 3 g / 1 dimethylamine borane and pH 8.5, nickel-plated.
  • a molded body with 40% carbon content with a cross section of 4 x 10 mm is produced from the nickel-plated yarn in an epoxy resin.
  • a shear strength of 46.6 N / m 2 was determined on the molded body.
  • a comparatively produced molded body made of non-nickel-plated carbon yarn had a shear strength of 33.2 N / m 2 .
  • Carbon fibers with a modulus of elasticity of 415 00 MPa and a tensile strength of 2350 MPa were nickel-plated in accordance with Example 1.
  • Test specimens with 50% by volume unidirectionally oriented fibers were produced from these fibers using a commercially available epoxy resin based on bisphenol A (cold-curing).
  • the ILS was 58 MPa.
  • a test specimen which contained 50% by volume of untreated carbon fibers had an ILS of 29.5 MPa.
  • Test specimens with a commercially available polyester resin (isophthalic acid type) as a matrix were produced from carbon fibers according to Example 2.
  • the test specimens also contained 50% by volume of fibers, unidirectionally oriented.
  • a test specimen which contained the same polyester resin but contained 50% by volume of untreated carbon fibers gave an ILS value of 24 MPa.
