  • Publication number: 20150137404
    Abstract: The invention relates to a novel process for commercial production of bulk functionally graded materials (FGM) with a per-determined axial, radial, and spherical gradient profiles. The process is based on the reiterated deformation of the layers of variable cross-section thicknesses made of different materials. That allows significant savings of time, energy and materials. Metals, ceramics, glasses and polymers in different combinations can be brought together with a continuous or stepwise gradual change from one material to another. The invention can be applied to industrial production of functionally graded materials with different types of gradient profiles, which cannot be produced by the existing technologies and which are sought by many key industries. The mechanical, thermal and optical responses of materials produced by the proposed methods are of considerable interest in optics, optoelectronics, tribology, biomechanics, nanotechnology and high temperature technology.

The vessel may be formed by providing a first fumed silica soot layer comprised of primary particles of fumed silica soot, and then providing over the first fumed silica soot layer a second fumed silica soot layer comprised of agglomerated particles formed into an agglomerated form from primary particles of fumed silica soot. The primary particles of the first fumed silica soot layer may have a substantially uniform density distribution, and the agglomerated particles of the second fumed silica soot layer may have a substantially non-uniform density distribution. The methods may include consolidating the first and second soot layers together to form a consolidated body.

  • Publication number: 20140066225
    Abstract: A golf putter head is made entirely of pottery clay and can have a glazed body and an unglazed striking face. This putter head is preferably fabricated by forming a basic disc shape on a potter's wheel and then removing a portion of the disc shape away to form a striking face. A putter with a mallet shaped head can be formed. After drying, the clay can be glazed and then fired. The putter head can alternatively be fabricated using a ram press molding technique.

  • Patent number: 8585947
    Abstract: A process for manufacturing a composite block of closed geometry, in the form of a continuous ring, based on fibers and on a crosslinkable resin, by continuous winding and superposition of several layers of a tape of reinforcement fibers embedded in a matrix based on a composition comprising a crosslinkable resin. The process comprises from upstream to downstream, the following steps: producing a rectilinear arrangement (12) of reinforcement fibers (11) and conveying this arrangement in a feed direction (F); degassing the arrangement (12) of fibers by the action of a vacuum (13); after degassing, impregnating said arrangement (12) of fibers under vacuum with said resin composition in the liquid state (17); passing the pre-preg thus obtained through a die (20) to make said pre-preg into the form of a tape (21) composed of reinforcement fibers (11) in their liquid resin (17) matrix, the thickness of said tape being less than 0.

  • Patent number: 8562901
    Abstract: The current invention provides a method to fabricate a crack-free continuous fiber-reinforced ceramic matrix composite by eliminating shrinkage stresses through a unique combination of freeze forming and a non-shrinking matrix composition. Cracks related to drying shrinkage are eliminated through freeze forming and cracks related to sintering shrinkage are eliminated by using a matrix that does not shrink at the given sintering temperature. After sintering, a crack-free ceramic composite is obtained.
