Claim 15:
16. 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 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; and
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 three dimensions having a plurality of x-fibers, a plurality of y-fibers, and a plurality of z-fibers,
wherein one or two of the plurality of x-fibers, the plurality of y-fibers, and the plurality of z-fibers comprises high temperature thermoplastic fibers and the other one or two of the plurality of the plurality of x-fibers, the plurality of y-fibers, and the plurality of z-fibers comprises metallic fibers;
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.
