Through further processes of graphitizing or stretching the fibres strength or elasticity can be enhanced respectively.
2.
"' Glassy carbon "'is a non-graphitizing, or nongraphitizable, carbon which combines glassy and ceramic properties with those of graphite.
3.
The preparation of glassy carbon involves subjecting the organic precursors to a series of heat treatments at temperatures up to 3000 �C . Unlike many non-graphitizing carbons, they are impermeable to gases and are chemically extremely inert, especially those prepared at very high temperatures.
4.
Lower-quality fiber can be manufactured using psi, 5, 650 MPa or N / mm?), while carbon fiber heated from 2500 to 3000 �C ( graphitizing ) exhibits a higher modulus of elasticity ( 77, 000, 000 psi or 531 GPa or 531 kN / mm?).
