本文采用尼龙1010盐专碳纤维预先复合、然后进行原位固态编聚的新方法,比较系流地研究了其反应历程和碳纤维对结晶尼龙1010基体的界面物理效应和化学效应。实验给果:尼龙1010盐——碳纤维复合物的固态缩聚转化率和粘度与反应温度和时间及氮气流速有密切关系。碳纤维对尼龙1010盐的原位编聚起着界面结晶成核和加速单位转化的催化作用。碳纤维表面固有的特性使尼龙1010盐固态缩聚有外延结晶的特征。在界面区域纤维表面可诱发尼龙1010形成横晶。在碳纤维表面还可以形成大量接柱的尼龙1010大分子,从而强化碳纤维——树脂的界面粘结。
In this paper, nylon 1010 salt special carbon fiber pre-composite, and then in-situ solid state aggregation of a new method, comparatively streamline to study the reaction process and carbon fiber on the crystalline nylon 1010 matrix physical and chemical interface effect. Experimental results: nylon 1010 salt - carbon fiber composite solid state condensation conversion and viscosity and reaction temperature and time and nitrogen flow rate are closely related. The in-situ intercalation of nylon 1010 salt by carbon fibers plays a catalytic role in interfacial crystallization nucleation and accelerated unit transformation. The inherent properties of carbon fiber surface nylon 1010 solid state polycrystalline epitaxial crystallization characteristics. Nylon 1010 can be induced to form transverse crystals at the fiber surface in the interface region. Nylon 1010 macromolecules with a large number of posts can also be formed on the surface of the carbon fiber to reinforce the carbon fiber-resin interfacial adhesion.
