ABSTRACT:
The present invention relates to a low-weight, high-strength composite pad, and a method of making the same. The composite pad has a substantially rigid board and at least one reinforcing coating on one or more sides of the board. The reinforcing coating has a foamable material with a fibrous fabric bonded thereto. At least one layer of a slurry mixture then covers the reinforcing coating. Also generally described, the method of making the present invention involves forming in a mold a reinforced core of the substantially rigid board, the foamable material, and the fibrous fabric, removing the reinforced core from the mold, and then applying the layer of slurry mixture thereto.
