摘要:
A method of making a composite sheet, a method of making composite component and a composite component are provided. The method of making a composite sheet includes providing a container, adding a binder to the container, adding a plurality of randomly oriented fibers to the binder in the container, and subjecting the container to motion to coat the plurality of randomly oriented fibers with the binder. The method includes curing the binder and coated plurality of randomly oriented fibers to form a composite sheet. The plurality of randomly oriented fibers of the composite sheet are interlocked within the binder. The composite has uniform strength in all planar directions.

Dense composites of dielectric material having high thermal conductivity and adjustable dielectric properties. The dense composites are composed of homogeneous mixtures of AlN and SiC with at least one member selected from the group consisting of Y2O3, La2O3, rare earth oxides, CaO and Li2O. These composites are ideally shaped into usable products such as traveling wave tubes and electronic accelerators for use in microwave environments.

摘要:
A monolithic self-constrained green body tape for use in low temperature ceramic co-firing is provided. The tape contains at least two layers: one low temperature ceramic layer containing particles of a glass, a ceramic, and an organic binder, and a self-constraining layer containing a refractory ceramic and a wetting agent for the glass in the first layer. When the tape is fired at a sintering temperature of the low temperature ceramic layer, densification occurs in the z (thickness) direction, but essentially no shrinkage (less than about 1%) occurs in the x-y planes. A method for forming a multilayer green body tape using simultaneous wet on wet ceramic slurry deposition is also provided. A dense, monolithic, low temperature, co-fired, self-constrained, multicomponent structure is also provided. The structure contains at least two multilayer ceramic substrates having electronic circuit components mounted thereon or therein. Each multilayer ceramic substrate contains at least two layers with one being a self-constraining layer.
