This invention is directed to the preparation of alloy articles consisting essentially of glass and/or glass-ceramic and an organic thermoplastic or thermosetting polymer having a working temperature compatible with that of the glass and/or the precursor glass for the glass-ceramic. The glass and polymer are combined at the working temperature to form an intimate mixture; i.e., the glass and polymer are in a sufficiently fluid state to be blended together to yield a body exhibiting an essentially uniform, fine-grained microstructure wherein, desirably, there is at least partial miscibility and/or a reaction between the glass and the polymer to promote adhesion and bonding therebetween. A body is shaped from the mixture and cooled to room temperature.
An alloy comprising a melt mixture of at least one glass and/or glass-ceramic and at least one organic thermoplastic or thermosetting polymer, said alloy exhibiting an essentially uniform, fine-grained microstructure comprised of polymer and glass and/or glass-ceramic elements wherein said microstructure is selected from the group consisting of:
An alloy comprising a melt mixture of at least one inorganic glass and/or glass-ceramic and at least one organic thermoplastic or thermosetting polymer, there being at least partial miscibility and/or a reaction between said glass and/or the precursor glass for said glass-ceramic and said polymer to promote adhesion and/or bonding therebetween, said alloy exhibiting an essentially uniform, fine-grained microstructure of polymer and glass and/or glass-ceramic elements wherein said microstructure is selected from the group consisting of:
A method for making an article of an alloy comprising a melt mixture of at least one inorganic glass and at least one organic thermoplastic or thermosetting polymer, the working temperature of said glass being compatible with the working temperature of said polymer, which comprises the steps of:
A method according to claim 53 wherein said glass consists essentially, expressed in terms of mole percent on the oxide basis, of 10-35% R.sub.2 O, wherein R.sub.2 O consists of at least one alkali metal oxide in the indicated proportion selected from the group consisting of 0-25% Li.sub.2 O, 0-25% Na.sub.2 O, and 0-25% K.sub.2 O, 12-55% ZnO, and 28-40% P.sub.2 O.sub.5, and 0.5-5% total of Y.sub.2 O.sub.3 and/or at least one oxide of a rare earth metal selected from the lanthanide group.
A method according to claim 53 wherein said thermoplastic polymer is selected from the group consisting of polyarylether ketones, polyphenylene sulfides, polyfluoro resins, polyetherimides, liquid crystal polyesters, polyethersulfones, polytetrafluoroethylenes, polyetherether ketones, polyetherketones, polyethylterephthalates, polybutylterephthalates, melamines, and polycarbonates.
A method according to claim 53 wherein said thermosetting polymer is selected from the group consisting of epoxy resins, silicone resins, polyimides, phenolics, and diallyl phthalates.
A method for making an article of an alloy comprising a melt mixture of at least one inorganic glass-ceramic and at least one organic thermoplastic or thermosetting polymer, the working temperature of the precursor glass for said glass-ceramic being compatible with the working temperature of said polymer, which comprises the steps of:
