Problems solved by technology

The heating device is installed in the component on the rear side in an invisible area and must then pass through both plastic shells and the air gap to heat the front side of the component, which leads to increased energy consumption and / or poor heating performance

Embodiment Construction

[0036] figure 1 A sectional view of a layered body 10 is shown, which is produced in a multi-component method and is used as a radome. The radome 10 may serve as an exterior covering member of the vehicle and cover a radar sensor 20 provided inside the vehicle. Radar sensor 20 arranged behind radome 10 cannot be seen from the outside of the vehicle.

[0037] The radome 10 has a base 11 . A resin layer 17 is applied to the surface of the substrate 11 facing away from the radar sensor 20 . A heating film 16 is arranged at least partially between the resin layer 17 and the substrate 11 . The outer surface of the resin layer 17 and thus the outer surface of the radome 10 can be tempered, in particular heated, by means of the heating film 16 in order to melt away deposits such as rainwater, ice or snow. Furthermore, the heating film can be controlled in such a way that a temperature is induced in the resin layer 17 at which a self-healing process is triggered by which damages, ...

Abstract

The invention relates to a method for producing a layered body (10) in a multi-component method, comprising the following steps: in a first production step, producing a substrate (11) from a transparent plastic, in particular from polycarbonate, and in a second production step, coating the substrate (11) with a transparent resin layer (17), in particular made of polyurethane.

Description

technical field [0001] The invention relates to a method for producing a layered body according to the preamble of claim 1 . Background technique [0002] In contemporary vehicle manufacturing, efforts have been made for some time to realize vehicles that move autonomously. Radar-based systems are used to detect objects located in the vehicle's environment. Current radomes (the covering in front of the front radar of the vehicle) comprise a multi-shell structure which generally comprises at least two injection molded parts which have to be joined to each other. The two individual parts are then joined (for example by gluing) to form a composite structure which must be designed to be sealed against the ingress of media in the final state. The heating device is installed in the component on the rear side in an invisible area and must then pass through both plastic shells and the air gap to heat the front side of the component, which leads to increased energy consumption and / ...
