A lightweight composite panel has two outer faces (4) either side of a wood-based core material (6). The core consists of crosspieces presented at an angle alpha to the inner faces of the outer facing materials. The core material (6) is chipboard, oriented strand board or fibreboard presented in a zigzag or corrugated pattern. The core material is bonded under light external pressure to the inner face of the facing materials by an adhesive. The angle alpha is preferably 15 to 85 degrees. Further claimed is a commensurate core material and a continually operated process for its manufacture and conversion to a lightweight board. The core peaks engage with matching grooves on the inner side of the facing material. |
