ABSTRACT:
A fiber reinforced core panel having a first side and an opposing second side. The core panel contains a series of adjacent low density strips having at least three faces and having a length to width aspect ratio of at least 5:1. The longitudinal axis of the low density strips are substantially parallel and the cross-section of each strip has a major face, a first edge face, and a second edge face. The major face of each strip is disposed within the first or second side of the core panel and the major face of each strip is disposed within an opposite face of the core panel than the major face of the adjacent strips. 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 reinforcement sheet forms at least about sixty five percent (65%) of the surface area of the first side of the core panel and at least about sixty five percent (65%) of the surface area of the second side of the core panel.
