摘要:
A hybrid material tension member for an elevator or other people transportation system using organic fiber and steel material as the load carrying components either discretely or in combined form. Several embodiments are disclosed.
摘要:
A fastener includes a composite body and a metal coupling attached to the body. The metal coupling includes an attachment structure to connect the fastener to an external structure.An assembly of components includes a first metallic component having a first coefficient of thermal expansion, a second non-metallic component having a second coefficient of thermal expansion different from the first thermal expansion and having a groove that receives a fastener that extends between the groove and the second component, the fastener slidably engaging the groove to accommodate relative expansion between the components.
摘要:
A fiber reinforced glass matrix composite article and a process for fabricating a fiber reinforced glass matrix composite article are disclosed. The article has an outer layer with selectively oriented continuous fiber reinforcement and an inner core having randomly oriented discontinuous fiber reinforcement. The process utilizes the hydrostatic pressure provided by injection molding of the discontinuous fiber reinforced core to fully consolidate the continuous fiber reinforced outer layer.
摘要:
A vane assembly has an outer support ring, an inner support ring, an outer liner ring, an inner liner ring, and a circumferential array of vanes. Each vane has a shell extending from an inboard end to an outboard end and at least partially through an associated aperture in the inner liner ring and an associated aperture in the outer liner ring. There is at least one of: an outer compliant member compliantly radially positioning the vane; and an inner compliant member compliantly radially positioning the vane.
摘要:
A composition for manufacturing a composite of a non-oxide ceramic matrix and a refractory phase within the non-oxide ceramic matrix includes a preceramic polymer for forming a non-oxide ceramic matrix and a refractory material dispersed within the preceramic polymer.
摘要:
An apparatus includes a thermoelectric (TE) device, a gas flow conduit proximate to one side of the thermoelectric device, a plurality of flexible tubes proximate to a second side of the thermoelectric device, and a spring to control contact force between the flexible tubes and the thermoelectric device. The spring comprises a coil spring at least partially circumscribing the gas flow conduit. The thermoelectric device converts a temperature differential between the flexible tubes and the gas flow conduit into electrical energy.
摘要:
A method of manufacturing a composite article includes pyrolyzing a preceramic polymer to form a non-oxide ceramic matrix and a byproduct, and reacting the refractory material with the byproduct to form a refractory phase within the non-oxide ceramic matrix.
摘要:
A fastener system provides an internal pocket within a CMC HEX panel into which a fastener stud is inserted through an internal pocket opening and loaded to secure the CMC HEX panel to a support structure.
摘要:
An electrical power generation system incorporates thermoelectric devices (TE Devices) for electrical power generation adjacent a flow path heat exchanger (HEX) adjacent to a vehicle flowpath structure such as a scramjet flow path to take advantage of the waste heat, high thermal gradients, and available, unused volume. A thermally conductive material communicates thermal energy from a vehicle external skin structure to the TE Device while a thermally conductive compliant material allows the TE Device to “float” with minimal mechanical stress.
摘要:
A process for applying an oxidation resistant coating to an article includes the steps of mixing at least about 10% by volume to up to about 99% by volume of a slurry at least one silica based material having a viscosity of about 1×102 poise to about 1×107 poise at a temperature of about 1,292° F. (700° C.) to about 3,272° F. (1,800° C.) at least about 1% by volume to up to about 90% by volume of the slurry at least one oxygen scavenger, and a liquid medium to form the slurry; coating an article with the slurry to form a slurry coated article; and heat treating under an inert atmosphere the slurry coated article to form an article having at least one oxidation resistant coating layer containing the at least one oxygen scavenger.
