Abstract
A helical tooling process for economical production of high quality, high temperature thermoplastic composite tubes uses a mandrel or external cylinder to resist a force applied from a helical member for consolidation pressure, compaction, and part removal. The helical too long process facilitates the prescription of a desired consolidation pressure and diameter, independent of temperature. The advantages of the disclosed process include improved produced part quality, increased process flexibility, and enhanced economic efficiency. These advantages stem from the device being easily controlled and fabricated and having a low thermal mass.
