Claim 13:
14. A floor panel assembly having a bottom surface and a top surface, the floor panel assembly comprising:
a first stack of structural layers adjacent the bottom surface;
a core layer, adjacent the first stack of structural layers, that absorbs shear stress;
a second stack of structural layers between the core layer and the top surface;
a heating layer between the core layer and the top surface; and
a first woven impact layer between the heating layer and the top surface, the first woven impact layer comprising:
a woven thermoplastic fiber matrix, wherein the woven thermoplastic fiber matrix has a melting point between melting points between 150 and 400 degrees Celsius; and
a 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.
