8 . The multi-layered panel of claim 7 , wherein the first fiber pattern includes a first fiber orientation and a first fiber concentration, and the second fiber pattern includes a second fiber orientation and a second fiber concentration, and wherein the first fiber orientation and first fiber concentration, and the second fiber orientation and fiber concentration are such that the first fiber pattern has a strength and/or a flexibility that is substantially different than the second fiber pattern.
9 . The multi-layered panel of claim 8 , wherein the third fiber pattern includes a third fiber orientation and a third fiber concentration, and the fourth fiber pattern includes a fourth fiber orientation and a fourth fiber concentration, and wherein the third fiber orientation and third fiber concentration, and the fourth fiber orientation and fourth fiber concentration are such that the third fiber pattern has a strength and/or a flexibility that is substantially different than the fourth fiber pattern.
10 . The multi-layered panel of claim 9 , wherein each of the first fiber orientation, the second fiber orientation, the third fiber orientation, and the fourth fiber orientation are one of a cross-linked diagonal pattern, a unidirectional pattern, or a bidirectional pattern.
11 . The multi-layered panel of claim 10 , wherein the first fiber reinforced plastic layer and the second fiber reinforced plastic layer are made of sheet fiberglass.
12 . The multi-layered panel of claim 11 , wherein the intermediate layer is a polyurethane layer.
