Abstract
A method of providing a unitary body comprised of two initially separate layers having similar coefficients of thermal expansion involves forming a mat of glass fibers in a configuration suitable for bonding the two layers together, placing the glass mat between them and heating the resulting stack to a temperature at which the individual fibers of the glass mat deform to form a continuous layer of glass which adheres to both layers, after which the stack is cooled to result in the unitary body.
