摘要

采用反气相色谱法对除浆前后T300B炭纤维的比表面积、溶解度参数和表面能进行了表征测试，分析了炭纤维表面物理特性对纤维和树脂浸润性能的影响。以一系列不同浓度的正庚烷为吸附质，根据BET吸附理论模型，计算得到除浆前后T300B纤维的比表面积分别为0.43m2/g和0.39m2/g。以正癸烷、正壬烷、正辛烷和正庚烷为非极性溶剂探针，甲苯、二氯甲烷、乙醇、1,4-二氧六环和丙酮为极性溶剂探针，采用DiPaola 和Guillet方法得到不同探针分子与纤维表面的Flory-Huggins相互作用参数，计算除浆前后T300B的溶解度参数(δ)分别为11.98MPa1/2和10.01MPa1/2。T300B纤维的上浆剂可以增大纤维表面能的极性分量，使上浆纤维的溶解度参数与E51环氧树脂的δ(11.78MPa1/2) 更为接近，提高了T300B纤维与树脂的浸润性能。

Abstract

Inverse gas chromatography was used to measure the surface area, solubility parameter and surface energy of T300B and desized T300B fiber, and the effect of surface physical characteristic on wettability between fibers and resin was investigated. A multiple of injection experiment with different concentration of hexane on fibers sample at 303K was carried out, and accordingly the surface areas of T300B and desized T300B were calculated as 0.43m2/g and 0.39m2/g, respectively, by BET method. Decane, nonane, octane and heptane were chosen as the neutral probes and toluene, dichloromethane, ethanol, 1,4-dioxane, acetone as polar probe, to determine the Flory-Huggins parameters (χ) between carbon fibers and probes. The solubility parameter (δ) of T300B and desized T300B was 11.98MPa1/2and 10.01MPa1/2respectively. The sizing could enhance the polar component of surface energy and the wetting ability of T300B fiber.
