A structural element (10) that includes a central part (12,13) formed of a fibrous material suspended in a thermoplastic matrix and at least one side part (14 or 16) formed of a fibrous material suspended in a thermoplastic matrix and having at least one void therein. The central part (12,13) and the at least one side part (14 or 16) are bonded together while in a heated thermoplastic state to form a single, integral structure (10) characterized by the absence of discontinuity across the bond plane of the structure. |
