Claim 12:
13. A method of making a heated floor panel assembly comprising:
aligning a first woven impact layer, a heating layer, a core layer, and one or more structural facing layers, wherein the first woven impact layer comprises a woven high temperature thermoplastic fiber matrix impregnated with a resin, wherein the resin is an epoxy, phenolic, bismaleimide, or cyanate ester resin;
bonding the first woven impact layer, the heating layer, the core layer, and the one or more structural facing layers to each other to form the heated floor panel assembly comprising:
a first stack of structural layers adjacent a bottom surface of the heated floor panel assembly
the core layer, adjacent the first stack of structural layers, that absorbs shear stress;
a second stack of structural layers between the core layer and a top surface of the heated floor panel assembly;
the heating layer between the core layer and the top surface;
the first woven impact layer between the heating layer and the top surface, the first woven impact layer comprising:
the woven thermoplastic fiber matrix, wherein the woven thermoplastic fiber matrix has a melting point between melting points between 150 and 400 degrees Celsius; and
the resin infiltrating the woven thermoplastic fiber matrix, wherein the resin is an epoxy, phenolic, bismaleimide, or cyanate ester resin,
wherein the first woven impact layer is woven in two dimensions having a plurality of x-fibers and a plurality of y-fibers,
wherein the plurality of x-fibers and the plurality of y-fibers alternate between high temperature thermoplastic fibers and metallic fibers such that the first woven impact layer comprises no more than 50% metallic fibers; and

a second impact layer between the first stack of structural layers and the core layer; and
a third stack of structural layers between the first woven impact layer and the second impact layer.
