A composite absorbent article comprises a reusable frame member for shaping and leakage control onto which a single-use absorbent device can be detachably connected and repeatedly replaced without the need to replace the reusable frame member. A low-cost, high-performance composite absorbent article
A composite absorbent article comprises a reusable frame member for shaping and leakage control onto which a single-use absorbent device can be detachably connected and repeatedly replaced without the need to replace the reusable frame member. A low-cost, high-performance composite absorbent article can thus be provided from low-cost single-use absorbent devices by virtue of the reusable frame member. A wicking barrier lining a central void or depression helps provide leakage containment for the overall composite absorbent article.
