摘要

摘要: 通过Wilhelmy吊片法测试液体与玄武岩、玻璃纤维单丝的前进接触角,应用OWRK理论计算得到纤维表面能及其色散与极性分量.实验研究表明:未经表面处理的玄武岩纤维表面能高于S-2玻璃纤维,去除浸润剂后2种纤维表面能的极性分量均明显降低,并且测试液体的极性分量对纤维表面能的测试结果影响甚大.分析结果为纤维与树脂的表面张力合理匹配、形成良好界面浸润和粘接提供了理论依据.

Abstract: The surface free energies and their dispersion/polar components of basalt and glass fiber were investigated using dynamic contact angle analysis. According to Fowkes′ and Good′s theory,by making use of the contact angle values for monofiber surfaces and standard liquids with known values of surface energy,surface free energy values as well as their components of both fibers were evaluated. It was found that the surface free energy of sized basalt fiber was higher than sized S-2 glass fiber while the polar component of both fibers tended to decrease without sizing; the liquid polarity also influenced the quantity of polar interactions as well as the quantity of dispersion interactions. These results indicate that sizing on the fiber improves wettability and interface adhesion between fibers and resin in fiber reinforced composites.
