ABSTRACT:
A wire/fiber ring having two layers applied in four clock positions. Each layer includes a first material strand having a first diameter and a second material strand having a second diameter different from the first diameter. A second or any subsequent layer is disposed such that there is unambiguous nesting between strands in adjacent layers. After the array is built-up, wire is over-wrapped around the array to hold it in place during subsequent consolidation steps, which take place after the built-up array is sealed in an air-tight container and evacuated. After heating and application of pressure a wire/fiber array having a void content of about 12% and a fiber content of between about 0% to 70% and preferably between about 30% and 45% can be achieved.
