要通过对日本东丽1700、T800碳纤维复丝拉伸性能的表征主要研究了加捻对，T800碳纤维拉伸性能的影响。研究结果表明：采用浸胶后加捻的方式有助于改善T800碳纤维的拉伸性能，合适的捻度可使其拉伸强度提高5％，断裂延伸率提高10％。并通过对rr800碳纤维干纱加捻的研究基本确定了T800碳纤维的临界捻度为15n／m。
要通過對日本東麗1700、T800碳纖維複絲拉伸性能的錶徵主要研究瞭加撚對，T800碳纖維拉伸性能的影響。研究結果錶明：採用浸膠後加撚的方式有助于改善T800碳纖維的拉伸性能，閤適的撚度可使其拉伸彊度提高5％，斷裂延伸率提高10％。併通過對rr800碳纖維榦紗加撚的研究基本確定瞭T800碳纖維的臨界撚度為15n／m。

By means of testing on the tensile properties of T700 and T800 carbon fibre made in Japanese Toray Company, the effect of twisting on the tensile properties of T800 carbon fibre is researched in this paper. The results show that the method of twisting after dipping is conductive to improve the tensile properties of T800 carbon fibre. The tensile strength can be improved by 5% and the elongation at break can be improved by 10% when the twist is 15 n/re. In additon, the critical twist of T800 carbon fibre can be determined as 15 n/m by the research on the twisting of T800 carbon fibre without dipping.
