The present invention resides in ignition resistant non-linear carbonaceous fiber or fiber tow having a reversible deflection ratio of greater than 1:1 but equal to or less than 1.2:1. The fibers have a multiplicity of crimps along their length with a crimp frequency on the order of from 6 to 15 crimps per inch. Fibers of the invention have an elongatability of from about 2 to about 9 %, a pseudo-elongatability of from about 0.2 to about 18 %, and a tenacity without a loss of elongation on the order of at least 6 g/d. The carbonaceous fibers can be used, for example, as thermal insulation and/or fire resistant insulation in vehicles, building structures or clothing in furniture coverings, carpets, and the like, and can be used alone or blended with other fibers to form fine yarns.
