Abstract
A method of coating a surface according to the present invention comprises the steps of abrading the surface to be coated with particles, then arranging a composite structure comprising a layer fibre fabric, a fibre bundle applied according to a pattern and particles of bioactive material in between the fibre bundles pattern, and a second fibre fabric. The method and coated implants manufactured by the method provide implants with good load bearing capabilities for use for example in hip implants.

A method of coating a surface, comprising the steps of
- abrading the surface to be coated with particles to form an abraded surface,
- forming and/or arranging a composite structure on the abraded surface, the composite structure comprising
- a first fibre fabric impregnated with a first resin,
- at least one fibre bundle impregnated with a second resin, the fibre bundle being arranged according to a pattern forming in-between spaces, and in contact with the first fibre fabric,
- particles of bioactive material arranged into said in-between spaces of the fibre bundle and arranged in contact with the first fibre fabric,
- a second fibre fabric impregnated with a third resin and arranged in contact with the fibre bundles and at least part of the particles of bioactive material, wherein the mesh size of the second fibre fabric is smaller than the average diameter of the particles of bioactive material,
- polymerising the resins of the composite structure.
