The invention relates to film laminates, formed from at least three layers A, B and C, each layer containing at least one plasticizer and at least one polyvinyl acetal, wherein, at least one of the layers A, B or C contains at least one polyvinyl (iso)acetal having a mean degree of polymerization of less than 3000, 10 to 25% by weight of polyvinyl alcohol groups and a proportion 50 to 80% by weight of polyvinyl (iso)acetal groups, and wherein layer B has a plasticizer content of less than 32% by weight. The film laminates can be used for the production of glass / film laminate / glass composites for motor vehicles, aircraft, ships, architectural glazings, façade components, or for the production of photovoltaic modules.

The present invention provides a functionally graded glass / ceramic / glass sandwich system for use in damage resistant, ceramic and orthopedic prosthesis. The functionally graded glass / substrate / glass composite structure comprises an outer residual glass layer, a graded glass-ceramic layer, and a dense interior ceramic. The functionally graded glass / substrate / glass composite structure may further comprise a veneer on an exterior surface. The present invention also provides a method for preparing a functionally graded glass / ceramic / glass sandwich system. A powdered glass-ceramic composition is applied to the accessible surfaces of a presintered zirconia substrate to thereby substantially cover the substrate surfaces. The glass of the composition has a CTE similar to that of the substrate material. The glass-ceramic composition is infiltrated into and densifies the substrate by heating the assembly to at least the sintering temperature of the substrate.

Film laminates are formed from at least three layers A, B and C, each containing at least one plasticizer and at least one polyvinyl acetal, wherein two outer layers A and C each contain at least one identical or different polyvinyl acetal having a proportion of polyvinyl alcohol groups of 18.5 to 23% by weight, at least one inner layer B contains a polyvinyl acetal having a proportion of polyvinyl alcohol groups of 12 to 18% by weight, and at least one of the layers A, B or C contains at least one polyvinyl (iso)acetal. The film laminates can be used for the production of glass / film laminate / glass composites for motor vehicles, aircraft, ships, architectural glazings, façade components, or for the production of photovoltaic modules.

Compositions and methods are described for transparent glass composite having nanoparticles therein that scintillate in the presence of nuclear radiation, particularly gamma rays, but also x-rays, alpha particles, beta particles, and neutrons. The transparent glass composites can be prepared by a melt / cool process to produce the transparent glass composite. The wavelength of light emitted by the transparent glass composite can be tailored based on the materials used to make the glass composite. A detector that utilizes the transparent glass composite can measure nuclear radiation from numerous sources.

The invention relates to a bulk metal glass composite material with stretching plasticity and work hardening capacity. A crystal phase capable of producing phase change is generated in the metal glass during deforming by alloy component control and cooling speed adjustment, and the crystal phase is deformed to produce the phase change so as to prepare the composite material. The bulk metal glass composite material with the stretching plasticity and work hardening capacity is prepared by taking common pure metal elements as main components, mixing the materials according to an atomic percentage expressed by an alloy component expression, and smelting and suction casting. The bulk metal glass composite material contains 10 to 60 volume percent of crystals. The bulk metal glass composite material of the invention can undergo the phase change during deforming, has higher strength and compression plasticity, particularly has higher stretching plasticity and work hardening capacity, and can meet the requirement of practical engineering application; therefore, the composite material has quite broad engineering application prospect.
