Abstract: The invention relates to a method and apparatus for separating a sheet of glass along a score line on the sheet. The method involves flexing the glass at the score line along an axis of flexure on a support member and prestressing the glass to a level below the critical stress level, and then applying a critical stress at or above the critical stress level to break the glass along the score line. The apparatus includes a support for the sheet, including a fulcrum defining an axis of flexure for alignment with the score line, and at least two pressure members spaced above and on each side of the score line. At least one of the pressure members or the fulcrum has a resiliently deformable cushioning surface thereon.

Abstract: An improved method for the fabrication of lightweight ceramic matrix composite panels, utilizing pressure forming with floating tooling to shape integral stiffeners such as raised integral surface channels on panel surfaces, is provided. The consolidation of green composite material against refractory floating tools by hot hydrostatic or isostatic (gas) pressing, followed by removal of the tooling, yields a strong, rigid, yet lightweight ceramic structure.

Abstract: A ceramic matrix composite article having a varying thickness is fabricated by a process wherein multiple prepreg sheets comprising reinforcing-fibers and powdered matrix material are stacked to provide a multi-layer prepreg stack wherein, through each cross-sectional dimension perpendicular to the plane of the sheets, the number of prepreg sheets contributing to the aggregate sheet thickness of the stack varies in proportion to the relative thickness desired in the layered article. The stack may consolidated to a composite article with a smoothly varying thickness profile without undue fiber breakage or ply wrinkling in the composite structure. consolidated into a composite article having a smoothly varying thickness profile with reduced internal fiber bowing or breakage. Preferably, the exterior surfaces of the article comprise long, substantially continuous fibers and are free of ply drops.

Abstract: Fiber-reinforced ceramic matrix composite articles of complex shape are made with improved physical integrity and control over fiber alignment by a process wherein prepreg comprising fibers and powdered matrix is treated to shorten the average length of the fibers, then configured without binder removal into a preform of selected shape and fiber orientation, and finally consolidated with heat and pressure into a dense ceramic matrix composite article. Fiber breakage during the consolidation process is thereby avoided.

Abstract: In the method for making a ceramic matrix composite article comprising the steps of providing a porous preform for the article formed of a combination of a fibrous reinforcing material and a ceramic matrix material, and thereafter consolidating the preform by the application of heat and consolidation pressure thereto, improved consolidation of preforms of curved or other complex configuration is achieved by applying consolidation pressure to the preforms through the medium of a softened glass.

Abstract: The present invention is directed to an apparatus (10) for grinding or polishing at least one edge of a glass substrate. The apparatus includes an air bearing support member (20) configured to pivot about an axis of rotation (12) with zero frictional resistance opposing said pivotal movement. A grinding unit (30) is coupled to the air bearing support member (20). The grinding unit (30) is configured to apply a predetermined force normal to the at least one edge to remove a predetermined amount of material from the at least one edge. The predetermined force is directly proportional to the predetermined amount of material and less than a normal force resulting in glass substrate breakage.
