Radome for vehicles and method for manufacturing said radome for vehicles
The radome ( 1 ) for vehicles comprises a first part ( 8 ) comprising a transparent layer ( 11 ) and at least one decoration layer ( 5, 6 ), a second part ( 10 ), and an intermediate part ( 9 ) placed between the first and second parts ( 8, 10 ), the intermediate part ( 9 ) being made from a thermoset compound. The method for manufacturing said radome comprises the following steps: inserting both the first and second parts ( 8, 10 ) in a mold; and injecting a thermoset compound between them for forming the intermediate part ( 9 ). It permits to provide a radome for vehicles with a better RF performance.
1 . A radome ( 1 ) for vehicles, comprising:
a first part ( 8 ) comprising a transparent layer ( 11 ), at least one decoration layer ( 5 ) and a protective layer ( 12 ), the protective layer ( 12 ) being made from a polyurethane or polyurea thermoset resin;
a second part ( 10 ) comprising a heating layer ( 18 ); and
an intermediate part ( 9 ) placed between the first and second parts ( 8 , 10 ), the intermediate part ( 9 ) being made from a polyurethane resin or polyurea resin,
wherein the intermediate part ( 9 ) joins the first part ( 8 ) and the second part ( 10 ), entirely filling the space between the rear face of the first part ( 8 ) and the front face of the second part ( 10 ).
2 . The radome ( 1 ) for vehicles according to claim 1 , wherein the radome ( 1 ) defines a field of view ( 7 ) in the first, second and intermediate parts ( 8 , 10 , 9 ), the intermediate part ( 9 ) being in contact with the first and second parts ( 8 , 10 ) at least in said field of view ( 7 ).
3 . The radome ( 1 ) for vehicles according to claim 1 , wherein the thickness of the intermediate part in its part with a minimum thickness, Ti, is greater than 0.1 mm.
4 . The radome ( 1 ) for vehicles according to claim 1 , wherein the transparent layer ( 11 ) comprises depressions ( 15 ).
5 . The radome ( 1 ) for vehicles according to claim 1 , wherein the intermediate part ( 9 ) comprises intermediate protrusions ( 16 ) with a thickness greater than the rest of the intermediate part ( 9 ).
6 . The radome ( 1 ) for vehicles according to claim 4 , wherein the second part ( 10 ) comprises rear protrusions ( 17 ) complementary with the depressions ( 15 ) of the transparent layer ( 11 ).
