摘要

The carbon fiber composites of thermally stable polymers which have aromatic and/or heterocyclic rings in their main chain were investigated by torsional free oscillation measurement. The composites were composed of two kinds of commercial varnishes, A and B, and four kinds of straight bundles of carbon filaments with different manufacturers, treated (a), non-treated (b), 6,000 filaments (c), and 12,000 filaments (d). The mechanical data were analyzed as Gillham's TBA technique. The results obtained are shown in Figs. 1~4. The relaxations obtained correspond to those observed on film samples.
