低温等离子体对连续玄武岩纤维改性研究

The research of low temperature plasma modification of properties of the GBF

针对连续玄武岩纤维表面光滑且呈化学惰性,纤维浸润性差导致与树脂基体复合粘结性较差的缺陷,实验采用低温等离子体法改性处理连续玄武岩纤维。在放电时间3 min,放电压强20 Pa条件下,改变放电功率,观察连续玄武岩纤维表面形貌、力学性能、表面摩擦因数和浸润性的变化。结果表明,随着放电功率的增大,连续玄武岩纤维断裂强度下降、摩擦因数增大和浸润性提高。

In view of the defects that continuous basalt fiber smooth surface and inert chemical property, poor fiber invasive leads to poor adhesion to the matrix composite, this experiment use low temperature plasma method to modify continuous basalt fiber. Discharge Time- 3min, Discharge pressure 20 pa, by changing the discharge power, observe the variation of continuous basalt fiber surface morphology, mechanical properties, surface friction factor and the invasive. The result shows, when increase the discharge power, continuous basalt fiber fracture strength will decrease, but both of friction factor and wettability will increase.
