THE PRESENT INVENTION DISCLOSES THE ENCAPSULATION OF A STACK (1,4; 1,14; 31, 34; 81, 82, 83) FORMED FROM A PLURALITY OF SHAPE FORMING MEMBERS EACH OF WHICH IS EITHER AT LEAST PARTIALLY FLUID PERMEABLE OR IS PERFORATED TO BECOMES SO. THE ENCAPSULATION IS BY ONE OR MORE LAYERS OF THERMOPLASTIC SHEET MATERIAL (7, 17, 27, 37, 47, 57, 87, 97, 107, 117, AND 127). BOTH A METHOD OF FABRICATING SUCH A LAYERED STRUCTURAL ARTICLE AND THE LAYERED STRUCTURAL ARTICLE ITSELF ARE DISCLOSED. THE STRUCTURAL ARTICLE HAS CONSIDERABLE STRENGTH EVEN THOUGH FABRICATED FROM INHERENTLY WEAK MATERIALS. |
