<p>An asbestos-free, unitary insulating member comprises two juxtaposed layers: a first layer of refractory material, and a thicker layer of thermoset resin filled with glass fibers. The first layer was fully cured separate from the second layer, and its inboard side has a relatively coarse surface. The two layers were joined to one another concurrently with the resin in the second layer being cured under pressure in a heated mold, whereby some of the resin penetrates the interstices of the coarse surface of the first layer to form a strong interlayer bond.</p> |
