Abstract
A hybrid article comprises a disintegrable metal comprising one or more of the following: Mg; Al; Zn; Mn; an alloy thereof; or a composite thereof; and a disintegrable polymer comprising one or more of the following: an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds; a cured cyanate ester; or a poly(hexahydrotriazine).
Claims30
A hybrid article comprising:
- a disintegrable metal comprising one or more of the following:
- Mg;
- Al;
- Zn;
- Mn;
- an alloy thereof;
- or a composite thereof;
- and
- a disintegrable polymer comprising one or more of the following:
- an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds;
- a cured cyanate ester;
- or a poly(hexahydrotriazine).
A method of manufacturing a hybrid article, the method comprising:
- forming a scaffold from a disintegrable metal comprising one or more of the following:
- Mg;
- Al;
- Zn;
- Mn;
- an alloy thereof;
- or a composite thereof;
- and
- forming a structure surrounding the disintegrable metal from a disintegrable polymer via molding or casting or forming a polymer part from the disintegrable polymer and attaching or fixing the polymer part to the scaffold, the disintegrable polymer comprising one or more of the following:
- an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds;
- a cured cyanate ester;
- a poly(hexahydrotriazine);
- or a precursor thereof.
A method of manufacturing a disintegrable hybrid article, the method comprising:
- combining a disintegrable metal power or shavings with a disintegrable polymer to provide a hybrid composition,
- the disintegrable metal powder comprising one or more of the following:
- Mg;
- Al;
- Zn;
- Mn;
- an alloy thereof;
- or a composite thereof;
- the disintegrable metal shavings comprising a metal composite which comprises:
- a cellular nanomatrix comprising a metallic nanomatrix material;
- and a metal matrix disposed in the cellular nanomatrix, and
- the disintegrable polymer comprising one or more of the following:
- an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds;
- a cured cyanate ester;
- a poly(hexahydrotriazine);
- or a precursor thereof;
- and
- molding the hybrid composition to form the disintegrable hybrid article.
A method of manufacturing a disintegrable hybrid article, the method comprising:
- forming a metal part from a disintegrable metal via an additive manufacturing method, the metal part having a plurality of pores;
- and
- disposing a disintegrable polymer in the pores of the metal part under a superatmospheric pressure or a subatmospheric pressure,
- wherein the disintegrable metal comprises one or more of the following:
- Mg;
- Al;
- Zn;
- Mn;
- an alloy thereof;
- or a composite thereof;
- and the disintegrable polymer comprising one or more of the following:
- an epoxy polymer derived from an epoxy base and a curing agent having cleavable bonds;
- a cured cyanate ester;
- or a poly(hexahydrotriazine);
- or a precursor thereof.
