<p>A composite board comprises a wood board (11) attached to a reinforcing plate (12,13) which comprises fiber-reinforced thermoplastic resin. The long continuous fibers of the thermoplastic resin are arranged in a single direction, and make up between 40% and 80% by weight of the resin. The use of a thermoplastic resin avoids the disadvantages inherent in the prior use of a thermosetting resin. <IMAGE></p>
