| 摘要 |
A composite stiffener (20) is fabricated using preforms (22, 24, 26, 28) of laminated, unidirectional composite tape. The stif fener includes a void (37) that is reinforced by a filler (36) wrapped with a structural adhesive (46). The surfaces of the preforms surrounding the void include a layer of composite fabric (48) which is bonded to the filler by the adhesive, thereby increasing the toughness of stiffeners around the void and improving pull-off strength of the stiffener. |
