A unitary, fiber-containing composite comprises (a) a first region (102) comprising a plurality of first binder fibers (114) and a plurality of bast fibers (118), (b) a second region (106) disposed above the first region, the second region comprising a plurality of second binder fibers (116) and a plurality of bast fibers, and (c) a transitional region (104) disposed betwe en the first region and the second region. The transitional region comprises concentrations of the first binder fiber (114), the second binder fiber (116 ), and the bast fiber (118). The concentration of the first binder fiber in the first transitional region is greatest proximate to the first region and leas t proximate to the second region, and the concentration of the second binder fiber and the bast fiber in the first transitional region is greatest proximate to the second region and least proximate to the first region. A method for producing a unitary, fiber-containing composite is also described . |
