摘要：
A stiffener (34 or 52 or 72) includes a pathway which allows gases and fluids, such as air, to be vented from the interface between surface bonding regions (35 or 60 or 74) of the stiffener and an adhesive (38 or 56 or 80) on a flexible substrate (36 or 54 or 78). The pathway may take the form of a porous material used for the stiffener or one or more bore holes (58 or 59 or 70) formed in the stiffener. The stiffener may also include an internal cavity (76) for promoting venting of fluids and gases. By venting fluid and gases from the adhesive/stiffener interface, better adhesion between the stiffener and flexible substrate is achieved.
