Abstract
A carbonisation study of a fibre derived from phenolic resin has been carried out. The carbon from this fibre is glassy in nature. The effect of both low and high temperature stretchings on the crystallite orientation has been investigated. Various degrees of preferential orientation could be observed in fibres prepared from the following treatments: (1) Carbonised under tension and heat-treated to 2750° C without tension, (2) Carbonised without tension but heat-treated to 2750° C under tension, and (3) Carbonised and heat-treated to 2750° C, both under tension. A significant increase in fibre modulus was observed in case 3. The mechanism by which preferential orientation is achieved and its relationship with increase in modulus are discussed.
