Abstract
The present invention is in a material for forming a backing for a thin metal shell of a metal-faced composite tool that is for use in manufacture of structural components utilizing advanced composites. The backing is a mix of a selected resin for providing support as to tool backing at its operating temperatures and pressures; and a mix of very small, larger low, and large higher aspect fibers that are combined to form a lattice. Which fibers, prior to combining with the resin, are treated for chemical adhesion. The fibers receive a volume of resin mixed therein sufficient to provide a strong bonding to and between the fibers. The cured backing to have a minimum density, exhibit low isotropic shrinkage during fabrication, with a low isotropic expansion at operating from room or atmospheric temperature to temperatures of from 350.degree. F. to 750.degree. F., and will exhibit good thermal conductivity and dimensional stability.
