Manufacturing method for lightweight large-size telescope mirror blanks and mirror blanks fabricated according to same
09810876 · 2017-11-07 ·

A method for manufacturing a mirror blank comprises: providing a primary piece of glass comprising a primary planar surface and a backing piece of glass comprising a backing planar surface; assembling a mirror blank assembly, wherein assembling the mirror blank assembly comprises interposing a plurality of glass splines between the primary glass and the backing glass. Interposing the plurality of glass splines comprises: for each glass spline, respectively abutting first and second opposed surfaces of the glass spline against the primary planar surface of the primary glass and against the backing planar surface of the backing glass. The mirror blank assembly is then heated to fuse the interposed glass splines to the primary glass and the backing glass while the primary glass and the secondary glass remain spaced apart from one another by the interposed glass splines to thereby provide the mirror blank.

Filament winding apparatus and method for ceramic matrix composites

An apparatus for making a composite article includes a monofilament feed track adapted to carry a spaced array of ceramic monofilament strands, a fiber yarn feed track adapted to carry a spaced array of fiber yarn tows impregnated with a plurality of glass particulates, a mandrel, and a heater assembly. The mandrel is adapted to wind together individual glass-impregnated fiber yarn strands and individual ceramic monofilament strands to form a dual-fiber weave. The heater assembly is adapted to heat at least the glass particulates such that pressure from the wound array of ceramic monofilaments is sufficient to consolidate the glass particulates and the dual-fiber weave into a dual-fiber ceramic matrix composite (CMC).

VEHICLE INTERIOR COMPONENT HAVING HIGH SURFACE ENERGY BONDING INTERFACE AND METHODS OF FORMING SAME
20240239275 · 2024-07-18 ·

Disclosed is a method of forming a vehicle interior component. In the method, a glass article is arranged on a forming surface of a forming surface. The glass article has a first major surface and a second major surface. The first major surface faces the forming surface, and the second major surface is opposite to the first major surface. The second major surface includes a region having a surface free energy of at least 35 mN/m. An adhesive is applied to the region of the second major surface of the glass article. The adhesive is contacted with a frame to attach the frame to the glass article.
