6. A sports racquet, according to claim 5 , characterized in that said first core member ( 251 ) comprises at least a first shaped wall ( 253 ) at said second bonding surface ( 251 B) and in that said second said core member ( 252 ) comprises at least a second shaped wall ( 254 ) at said third bonding surface ( 252 B), said first shaped wall and said second shaped wall forming said at least a first cavity ( 22 A, 22 B) when said first and second core members are bonded together.
7. A sports racquet according to claim 1 , characterized in that it comprises a supporting frame ( 50 ).
8. A sports racquet, according to claim 7 , characterized in that said supporting frame ( 50 ) comprises at least a first hollow frame member ( 501 ) extending at least partially through said paddle portion and forming said at least a first cavity ( 22 A, 22 B).
9. A sports racquet according to claim 8 , characterized in that said at least a first frame port is positioned at one end of said first hollow frame member.
10. A sports racquet according to claim 8 , characterized in that said supporting frame ( 50 ) comprises at least a second frame member ( 502 ) defining an external rim, which contours at least partially said paddle portion.
11. A sports racquet according to claim 7 , characterized in that said supporting frame ( 50 ) comprises at least a second frame member ( 502 ) defining an external rim, which contours at least partially said paddle portion.
12. A sports racquet according to claim 11 , characterized in that at least a second frame member comprises a single tubular element ( 502 A).
13. A sports racquet according to claim 11 , characterized in that said at least a second frame member comprises two or more tubular elements ( 502 B, 502 C), which are joined together to form a common wall ( 502 D), which is interior to said at least a second frame member ( 502 ).
14. A sports racquet according to claim 11 , characterized in that said second frame member is provided with at least a first frame port ( 5020 ).
15. A sports racquet according to claim 14 , characterized in that said at least a first frame port is positioned at one end of said first hollow frame member.
16. A sports racquet according to claim 1 , characterized in that said paddle portion comprises at least a second cavity ( 23 ) having a second longitudinal axis ( 231 ), which that is substantially perpendicular to said main reference plane ( 101 ).
17. A sports racquet according to claim 1 , characterized in that said at least a first cavity ( 22 A, 22 B) has a first longitudinal axis ( 221 A, 221 B) that is substantially parallel to said main reference plane ( 101 ).
