一种复合材料增韧细棒的涂层方法
摘要：
本发明关于一种复合材料增韧细棒的涂层方法，属于复合材料表面改性技术领域。该涂层方法包括以下步骤：首先，浸润树脂的纤维束穿过小孔初成型模具，形成圆形的截面形状；然后，穿过内部存有碳纤维粉涂料的涂层室；第三，细棒经过不直接接触的吸尘装置，表面粘结不牢固的碳纤维粉将被去除；第四，细棒经过预热装置和加热装置进行预热和凝胶；第五，细棒经过定型模具进行定形；第六，细棒经过加热装置进行固化；最后，细棒经过带有细毛刷的吸尘器再次将细棒表面粘结不牢固的纤维粉去除。本发明的涂层方法可在细棒生产过程中实现，将纤维粉作为涂料，利用被涂层复合材料自身的粘结性能，无化学残留，无单独的涂层工序，方法简单，效率高。
摘要（英）：

The invention relates to a coating method of a composite toughened slender rod, and belongs to the technical field of composite surface modification. The coating method comprises the following steps that firstly, fiber bundles soaked in resin penetrate through a small hole primary forming mold, and the circular section shape is formed; secondly, the fiber bundles penetrate through a coating chamber with carbon fiber powder coating stored inside; thirdly, the slender rod passes through a dust collection device which does not make direct contact with the slender rod, and carbon fiber powder which bonded to the surface infirmly are removed; fourthly, the slender rod passes through a preheating device and a heating device for preheating and gelling; fifthly, the slender rod passes through a shaping mold for shaping; sixthly, the slender rod is solidified through the heating device; and finally, the slender rod passes through a dust collector with fine bristle brushes, and fiber powder bonded to the surface of the slender rod infirmly is removed. The coating method can be achieved in the production process of the slender rod, the fiber powder is used as the coating, the bonding performance of coated composites is used, chemical residues are avoided, a separated coating procedure is omitted, the method is simple, and the efficiency is high.
