Abstract
A fiber reinforced core panel having natural contour contains a series of adjacent low density strips where the longitudinal axes of the low density strips are substantially parallel. The major face of each strip is disposed within the first or second side of the core panel. The core panel also contains a continuous fibrous reinforcement sheet which is threaded through the low density strips such that the fibrous reinforcement sheet is disposed between adjacent strips and adjacent to the major faces of the low density strips. The fiber reinforced core panel contains a natural contour in the direction perpendicular to the longitudinal axes of the low density strips, a natural contour in the direction parallel to the longitudinal axes of the low density strips, or a natural contour in both the directions parallel and perpendicular to the longitudinal axes of the low density strips.
