本发明提供了一种树脂基纤维增强复合材料的制备方法,包括：将连续纤维进行预处理,得到处理后的连续纤维；将纳米填料溶解于溶剂中,超声,得到纳米分散液；将处理后的连续纤维与静电发生器相连,浸入纳米分散液中,超声,干燥后得到纳米改性的连续纤维；将树脂对纳米改性的连续纤维进行浸润,固化,得到树脂基纤维增强复合材料。本发明通过在连续纤维表面静电吸附纳米填料,由于纳米颗粒吸附在纤维表面,在纤维表面形成凹凸起伏结构,纤维表面粗糙度进一步增加,纤维表面粗糙度的显著提高有利于增大纤维与基体树脂之间的接触面积,提高其浸润性能及其与树脂基体间的界面粘结强度,提高树脂基纤维复增强复合材料力学性能。

The present invention provides a method for preparing a resin-based fiber-reinforced composite material, which includes: pretreating continuous fibers to obtain treated continuous fibers; dissolving nano fillers in a solvent and ultrasonicating to obtain a nano dispersion; The continuous fiber is connected with an electrostatic generator, immersed in a nano dispersion liquid, ultrasonically, and dried to obtain a nano-modified continuous fiber; the resin is infiltrated and cured on the nano-modified continuous fiber to obtain a resin-based fiber-reinforced composite material. In the present invention, nano-fillers are electrostatically adsorbed on the surface of the continuous fiber. Because the nano-particles are adsorbed on the surface of the fiber, a concave and convex structure is formed on the surface of the fiber, the fiber surface roughness is further increased, and the significant increase in the fiber surface roughness is beneficial to increase the fiber and matrix resin The contact area between them improves the wettability and the bonding strength of the interface with the resin matrix, and improves the mechanical properties of the resin-based fiber-reinforced composite material.
