ABSTRACT:
A chopped fiber reinforced glass or glass-ceramic matrix integral structure having no bond lines. The structure comprises a face plate, a back plate, and a grid array of chamber walls. The face plate connects to the back plate through the chamber walls forming a grid array of chambers. The back plate has an array of apertures that lead to the chambers. The structure is fabricated by disposing at least two mold inserts in a mold housing having a bottom and sides. The mold inserts are in contact and in an array that follows the surface contours of the mold. The mold inserts and mold insert array is not capable of lateral movement. Heated chopped glass or glass ceramic impregnated fibers are displaced into the mold under pressure to form a composite. The composite is cooled and the mold inserts are removed by chemical dissolution.
