Abstract
Methods for consolidation and densification of fibrous monolith composite structures are provided. Consolidation and densification of two- and three-dimensional fibrous monolith components having complex geometries can be achieved by pressureless sintering. The fibrous monolith composites are formed from filaments having at least a first material composition generally surrounded by a second material composition. The composites are sintered at a pressure of no more than about 30 psi to provide consolidated and densified fibrous monolith composites.
Claims8
A process for consolidation and densification of fibrous monolith composite materials comprising:
- a. providing a fibrous monolith composite material including a first uniformly suspended mixture forming a central portion and a second uniformly suspended mixture forming a boundary portion, the first uniformly suspended mixture generally surrounded by the second uniformly suspended mixture,
- b. heating the fibrous monolith composite material at a first temperature below at least one of the melting temperatures of the first and second uniformly suspended mixtures, and
- c. holding for a period of time before heating to a second temperature greater than the first temperature, at a pressure of between about 1 to about 30 psi, to consolidate and densify the first and second uniformly suspended mixtures.
