碳纤维复合材料是一种高性能、多功能的先进复合材料,由于碳纤维表面光滑、表面能低与树脂基体粘接性能差,制约了碳纤维性能的发挥。因此,碳纤维表面改性成为提高其复合材料性能的重要途径。
有关碳纤维表面改性的方法比较多,其中冷等离子体技术是提高其界面粘接性能的简单有效的方法。
等离子体轰击纤维表面时可引起纤维表面的刻蚀,从而增加纤维与树脂基体的机械嵌合力;此外,等离子体与纤维表面作用时可引起纤维表面化学键发生断裂重组,从而在纤维表面引入极性基团,增加了纤维与树脂基体的相互作用。
对碳纤维表面进行适当的等离子体处理,会提高其表面的氧元素与碳元素之比,从而加强了纤维表面与树脂基体之间的化学键合,达到了增强复合材料界面性能的目的,10min应该是最佳处理时间。经过等离子体处理后,纤维表面基团被激发而产生的活性基团和自由基,破坏了树脂基体PPESK分子中的化学键,与其中的氧原子、氮原子结合,产生新的化学键,增强了纤维表面与树脂基体间的键合,从而提高了复合材料的界面性能。

As for composite materials of the fiber of the carbon, hanging, and sticking to the body of the radical of the resin low and taking and tie of the performance of energy on the surface of hanging with advanced composite materials that it was efficient and one kind of is multifunctional for the surface of the fiber of the carbon were bad, and restricted the development of the performance of the fiber of the carbon. Therefore, the surface of the fiber of the carbon becomes an important road where the character is mended and the performance of the composite materials is improved. There are compare it a lot of mending the method of the character for the surface of the fiber of the carbon, and the technology of cold plasma in that improves the interface, sticks, and ties an easy, effective method of the performance.

The keyboard while the atom of inside oxygen and the atom of nitrogen tie, it gives birth to a new bond, and the surface of the fiber and the body of the radical of the resin were strengthened corresponds, and, as a result, the performance in the interface of composite materials has been improved.

The compound material of the carbon fiber is a kind of high performance, multi-function advanced compound material, because of the carbon fiber surface smooth, the surface ability is low to glue with the resin body to connect the function bad, check and supervision the carbon fiber function of exertive.Therefore, the carbon fiber surface changes important path that sex becomes raising its compound material function.
The relevant carbon fiber surface changes the method of sex more and much, among them, cold etc. ion body technique is simple and valid method that raises its interface to glue to connect the function.
Wait the ion body bombard the hour of the fiber surface and can cause the engrave of the fiber surface eclipse, thus increasing the machine resultant force of the fiber and the resin body;In addition, the ion body and hour of the fiber surface functions of etc.s can cause the fiber surface chemistry key occurrence to split the reorganization, thus leading into the pole regiment in the fiber surface, increasing the interaction of the fiber and the resin body.
Carry on appropriate etc. ion body processing to the carbon fiber surface, the oxygen chemical element and the carbon chemical element that will raise its surface than, thus strengthenned the chemistry key between the fiber surface and the resin body to match, come to a to strengthen compound purpose of the material interface function, the 10 mins should be the best processing time.After passing by to wait the ion body processing, the live regiment of and free radicalses that the fiber surface regiment is stir up but produce, broke the chemistry key within the resin body PPESK member, combine with oxygen atom, the nitrogen atom in which, produce the new chemistry key, the key that strengthenned the fiber surface and the resin bodies match, thus raising the interface function of the compound material.

The carbon fiber compound material is one kind of high performance, the multi-purpose advanced compound material, because the carbon fiber surface is smooth, the surface ability lowers with the resin substrate cementation energy balance, has restricted the carbon fiber performance display. Therefore, the carbon fiber surface modification becomes enhances its compound material performance the important way. The related carbon fiber surface modified method quite are many, cold plasma technology is enhances its contact surface cementation performance the simple effective method. The plasma shells when the textile fiber surface may cause the textile fiber surface sculpture, thus the increase textile fiber and the resin substrate machinery inlays the joint effort; When, plasma and textile fiber surface action may cause the textile fiber surface chemical bond to have the break reorganization, thus in the textile fiber surface introduction polar groups and bases, increased the textile fiber and the resin substrate mutual function. Carries on suitable plasma processing to the carbon fiber surface, can enhance its superficial ratio of the oxygen element and the carbon element, thus strengthened between the textile fiber surface and the resin substrate chemistry linkage, had achieved the enhancement compound material contact surface performance goal, 10min should be the best process time. After plasma processing, the textile fiber surface groups and bases are stimulated the active groups and bases and the free radical which produces, destroyed in the resin substrate PPESK member chemical bond, if the center oxygen atom, the nitrogen atom union, produces the new chemical bond, strengthened the textile fiber surface and the resin substrate linkage, thus enhanced the compound material contact surface performance.
