Methods related to forming superabsorbent composite core structures using superabsorbent materials, such as superabsorbent polymers (SAP). In one method superabsorbent material is sprayed simultaneously with an adhesive to form a superabsorbent layer adhered to a first flexible sheet of material. A second flexible sheet of material is applied to the superabsorbent layer to position the superabsorbent layer between the first and second flexible sheets of material. At least one of the first or second flexible sheets of material is liquid permeable to allow liquid to penetrate into the superabsorbent layer from outside the composite product.
