Beschreibung
Zusammenfassung:	A mass isolation joint for electrically isolating a downhole tool includes a first joint section having a distal end in which a first thread is formed, a second join t section, and an insulating composite structure coupling the first joint section to the secon d joint section, wherein at least one of the first and second joint sections is adapted for coupling to the downhole tool. The insulating composite structure includes a first composite layer formed on the second joint section. The first composite layer has a second thread whic h engages the first thread on the distal end of the first joint section.
