等离子体处理对BFRP增强结构用集成材胶合性能的影响

Effects of Plasma Treatment on Bonding Properties of BFRP Reinforced Structural Glulam

通过改变空气等离子体设备的功率、离子焰口距离、传送速度,对玄武岩纤维增强复合材料(BFRP)表面进行等离子体处理,并将处理后的BFRP与樟子松进行胶合。经等离子体处理后板材胶合性能明显改善,达到了标准要求。通过SEM、FTIR等方法对处理后BFRP进行分析,初步解释了等离子体处理能提高胶合性能的原因:等离子体处理BFRP后,材料表面发生化学变化,且对表面起到刻蚀作用,从而使BFRP表面化学与物理性能得到改善。

The surface of the basalt fiber-reinforced polymer （BFRP） was treated with the plasma by changing the power of the air plasma equipment, the distance of the plasma flame and the speed of the transmission, and then glued the treated BFRP and the Pinus sylvestri （Pinus sylvestris var）. The plasma treatment significantly improved gluing performance that reached the standard requirements. The researchers analyzed the treated BFRP using the methods such as SEM, FTIR etc, which primarily explained the reason why the plasma treatment can improve the gluing performance： the plasma treatment of the BFRP causes the chemical reaction and has the etching effects on the surface of the material, which improves the chemical and physical properties of the surface of BFRP.
