Definitions
- the invention relates to a method for producing composite material components from at least one substrate and a number of supports provided with a thermoplastic, in which the substrate and the supports are brought into contact at least in places, and then at least the thermoplastic is heated up to a welding temperature and then the substrate and the supports are welded together under pressure, and a device suitable for carrying out this method.
- thermoplastic for example in the form of tapes
- the tapes and the substrate are heated up when they are put down and then pressed against one another, so that welding takes place between the tape and the substrate.
- This process is also known as thermoplastic tape laying.
- Infrared sources, laser sources and hot air are used to heat tape and / or substrate.
- substrate thus encompasses on the one hand the contour-giving molding tool for the component (application of the first layer of tapes to the molding tool) and on the other hand the semi-finished component with more than one tape layer.
- the substrate can also be a plastic component that was produced in another art processing method, for example an extruded tube or a container from a blow molding or rotational molding method.
- a molded body made of foamed material can also be used as the substrate, which remains in the finished component and fulfills certain functions, such as sound or thermal insulation.
- such components are also used in the context of highly dynamic applications as well as for pipes and pressure vessels. Due to their X-ray transparency, such components are also used in medical technology. In general, the components mentioned are characterized by extreme rigidity and strength with minimal weight at the same time.
- the above-mentioned common heat sources are arranged on so-called tape laying heads, which control the laying speed, the contact pressure and the laying position.
- the tapes and the substrate are heated by radiation or by convection.
- the thermal inertia when heating the substrate is to be regarded as disadvantageous: in order to achieve high installation speeds, the heating sources are worked with temperatures that are far above the processing temperature (melting temperature) of the thermoplastic. This means that the laying speed is limited because the material is thermally damaged if the temperature is too high. Since part of the heating power is also reflected by the material to be heated, temperature measurement with an infrared thermometer is not possible and, in particular, cannot be used to control the heating power. This applies above all to the infrared sources and hot air heaters mentioned. Laser sources, which allow the best power control according to the state of the art, are very expensive, especially when large heating powers are required, and, moreover, have only a low efficiency.
- the object of the invention is to create a method and a device of the type mentioned in the introduction to avoid the disadvantages mentioned above, which are characterized by lower energy consumption and lower investment costs in the production of composite materials.
- thermal damage to the material is to be avoided and a higher laying speed than with previously known methods or devices is to be achieved.
- This object is achieved in a method of the type mentioned in the introduction in that the energy required for heating is supplied in the form of microwave energy. Accordingly, it is provided in a device of the type mentioned at the outset that it has a microwave radiator for heating the thermoplastic.
