Definitions
- the invention relates to a method for preparing plastic surfaces, preferably surfaces of carbon fiber reinforced plastics, for further processing of structural parts to be carried, in particular to wing of aircraft, by abrasive removal of the surface.
- the surfaces intended for further processing by gluing are first ground and complex quality assurance measures are taken to check the grinding result.
- a waterbreak test is carried out, which uses the different surface tension of ground and contaminated surfaces to make a statement about the quality of the grinding result.
- the adhesive surface is completely wetted with deionized water. Then the surface is placed vertically so that the water can drain off. When the surface is well cleaned, the water flows off evenly. Pearls of water form in contaminated areas. Such spots have to be reground. To remove the water or any residual moisture, the parts must still be dried in the oven.
- the object of the invention is to propose a method for the preparation of plastic surfaces, preferably surfaces of carbon fiber reinforced plastics, for the further processing of structural parts to be carried, in particular to wing of aircraft, by abrasive removal of the surface, which reduces the risk of cutting through fibers but at the same time Enables higher bond strength with less rework.
- This object is achieved in the generic method in that the removal is carried out by blasting the surface by means of a blasting agent distributed in a gaseous fluid.
- a blasting agent distributed in a gaseous fluid.
- the quality of this surface even exceeds that of a ground surface.
- breaking attempts the components fail not at the gluing point, but in the base material, which advantageously increases the load-bearing capacity of the glued structural parts.
- Contamination of the mechanically cleaned surface by the fluid is advantageously avoided in that the gaseous fluid is dried and de-oiled air.
- blasting agent is applied to the surface to be treated by means of a low-pressure jet, preferably from a pressure vessel with less than 2.5 bar.
- the measure serves the same purpose in that the abrasive is applied to the surface to be treated by means of a vortex jet nozzle.
- the rotating jet of the vortex jet nozzle prevents the formation of so-called hot spots.
- An optical control of the work result is advantageously sufficient to ensure a sufficient surface quality.
- the treatment with the abrasive is carried out until an almost cloud-free matt treated surface is reached. This quality is advantageous in accordance with DIN EN ISO 12944-4 SA 2.5 on the Work result defined. Extensive waterbreak tests with drying steps in complex, large ovens can be omitted.
- a quality control of the treated surface is carried out by measuring a surface resistance and / or by optical control using a comparison sample.
- the reproducibility of the work result is further improved if the treatment is carried out in an air-conditioned, preferably draft-free environment.
- the surface is vacuum-packed for transport.
- Such packaging is already sufficient to transfer the operation according to the invention from the dust-sensitive component assembly to external suppliers.
- the statistical stability of the work result with its qualitative advantages is further improved if the abrasive is not circulated.
- the preparation by means of magnetic separators is not possible with the plastics to be treated with the method according to the invention, since they are non-magnetic. You must therefore use Air sightings or flotation. The lack of preparation also saves these process steps.
- the object is also achieved, in particular, by a semi-finished product, preferably made of carbon fiber reinforced plastic, with a structural part to be carried for further processing
- prepregs are pretreated according to the invention in the pressure jet process for gluing, for example using stringers on outer skins, adhesive bonding, ribs, fittings, etc.
- the process results in low material removal without the dimensional accuracy of the component being impaired. It cleans the surface by mechanically removing the surface, which, however, can be metered precisely in a particularly advantageous manner. There is an approx. 10-fold security against damage to the fibers of the plastic.
- the blasting treatment is carried out dry, the effect on the component surface being largely determined by the choice of the blasting agent.
- the surface roughness is primarily determined by the abrasive and the pressure.
