Historically, the growth of tubular carbon fibers involves a time-intensive batch process. Recent advance has lead to continuous growth of carbon tubes which exhibit several unique characteristics. In this study, we have investigated the microstructure of carbon tubes produced by a continuous process. It was observed that carbon tubes can be produced by continuous process with microstructure similar or superior to that produced using laboratory scale techniques. The result also encourages the improvement of carbon nano tube (CNT) production due to the similarities between micro-sized carbon tubes and CNT.
