<p>The present invention relates to composite building panels (1) of the kind comprising two parallel opposed spaced apart facing sheets (2) having an intermediate core of cementitious material (3) adhered therebetween. Panels according to the invention include a reinforcing bridging member (4) that is disposed between the facing sheets and which is at least partially embedded within the cementitious core. This bridging member (4) has an ultimate shear strain to failure that is greater than that of the cementitious core. The reinforcing bridging member increases both the bending strength and impact strength of the panels, the cementitious material helping to prevent the bridging member from failing due to buckling. This allows the use of relatively light reinforcing sections. Furthermore, the reinforcements can be advantageously positioned along the edge of the panel to provide a means of jointing the panels.</p> |
