Abstract

Computer controlled fiber coating chemical vapor deposition system and method for generating substantially uniform coated fibers by maintaining chemical vapor deposition reactor temperature in real time. Reactor temperature is monitored by in situ temperature sensors. Reactor temperature is sensitive to oxygen levels and oxygen levels within the reactor are varied in response to temperature sensor data. Closed loop process control software maintains reactor temperature at a preselected value resulting in predictable fiber coatings of a preselected thickness, crystallinity and chemistry.
