Abstract
A method for forming a ring structure having a high volume fraction of a filament reinforcement within a metal matrix is disclosed. The ring structure is formed by consolidating a set of nested rings each of which has a high volume fraction of the filamentary reinforcement therein. The nesting is done to provide a clearance between the rings of the nest of about 2 or 3 mils. The nested rings are enclosed within a HIPing can and the structure is HIPed at about 15 ksi and 1000.degree. C. for over an hour. A single superring structure results from the HIPing.
