Abstract
A rigid composite structure includes a tubular body made from a metallic material and having a first bore formed therein along a longitudinal axis, and one or more segments formed from a super hard material disposed within the first bore. Each segment has a hole formed in the center thereof, and the segments may be positioned end-to-end and adjacent to one another to align the center holes about the longitudinal axis and form a second bore. The segments can be held under compression within the first bore of the tubular body. The segments may be made of super hard materials such as natural diamond, synthetic diamond, polycrystalline diamond, single crystalline 10 diamond, cubic boron nitrate or other superhard composite materials which exhibit low thermal expansion rates and are generally chemically inert. The resultant rigid composite structure may possess higher tolerances to high pressures and high temperatures within the second bore.
