摘要
通过对日本东丽T700、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T800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15 n/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.
