Abstract
A structural panel comprises a metal and fibrous composite in which the metal outer skins have a minimum thickness of 0.005 in. exceeding foils and a maximum thickness of 0.012 in. while the fibrous core ranges between 0.01 in. and 0.05 in. The panel is a stiff, lightweight substitute for thicker metals and may replace light metal sheets such as aluminum with a composite in which the metal skins comprise sheets from heavier metals such as steel. The fibrous core is a web which is adhesively bonded to the metal skins and which has a plurality of weight-reducing openings formed therein to form a structural laminate having comparable strength to steel sheets of greater weight.
