Abstract
A mold in accordance with the present invention can be formed by a method which utilizes a fiber reinforced pre-ceramic resin composite which is cured and fired to form a Continuous Fiber Ceramic Composite (CFCC), or alternatively by use of a pre-ceramic matrix composite, which is cured, but not fired into a ceramic state.
Claims27
A thermoset mold prepared in accordance with a method which comprises the steps of:
- (a) forming a multi-ply, preform composite comprising,
- i) a pre-ceramic polymeric resin matrix,
- ii) a heat resistant, reinforcing, fabric substrate, and
- iii) at least one binder;
- and
- (b) curing the multi-ply composite pre-form of step (a) at a temperature in the range of from about ambient temperature to about 350.degree. F. on a plug to form a thermoset mold.
A ceramic mold prepared in accordance with a method which comprises the steps of:
- (a) forming a multi-ply, preform composite comprising,
- i) a pre-ceramic polymeric resin matrix,
- ii) heat resistant, reinforcing, fabric substrate, and
- iii) at least one binder;
- (b) curing the multi-ply composite pre-form of step (a) at a temperature in the range of from about ambient temperature to about 350.degree. F. on a plug to form a thermoset mold;
- and
- (c) firing the thermoset mold of step (b) at an elevated temperature for a period of time to form a reinforced ceramic mold.
A mold comprising a shaped body comprised of successive layers of a combination of inorganic materials, a pre-ceramic, polymeric matrix, a binder and a reinforcing fabric substrate.
A mold fired into a ceramic comprising:
- a shaped body comprised of successive layers of a combination of inorganic materials, a pre-ceramic polymeric matrix, a binder and a fabric reinforcing substrate.
A mold comprising a shaped body comprised of multiple layers, each of said layers including,
- i) a pre-ceramic polymeric resin;
- ii) at least one binder, said resin and binder forming a matrix;
- and
- iii) a heat resistant, reinforcing fabric substrate impregnated with said matrix.
A mold comprising a shaped body of multiple layers, each of said layers including,
- i) a pre-ceramic polymer resin,
- ii) at least one binder, said resin and binder forming a matrix, and
- iii) a heat resistant, reinforcing fabric substrate impregnated with said matrix.
- wherein at least two of said multiple layers include a different binder.
A mold comprising a shaped body comprised of successive layers of a combination of inorganic materials, a pre-ceramic polymeric matrix, a binder and a reinforcing fabric substrate wherein said first mold layer includes inorganic whisker materials to deter fissure formation on the surface of the mold and a smooth and finely textured fabric substrate.
A ceramic mold comprising a shaped body comprised of successive layers of a combination of inorganic materials, a pre-ceramic polymeric matrix, a binder and a reinforcing fabric substrate within said inorganic materials which is first cured at a temperature of from about ambient temperature to about 350.degree. F. to form a thermoset mold and which is fired after curing at a temperature between about 200.degree. F. and about 1100.degree. F. to form a ceramic mold.
