【摘要】 采用等离子技术对碳纤雏(CF)进行接枝芳基乙炔(PAA)处理,研究了影响CF/PAA复合材料层间剪切强度(ILSS)的因素。结果表明,经等离子接枝PAA处理后。复合材料的ILSS有了很大提高。SEM显示经接枝处理后CF和PAA树脂之间的界面结合紧密,改善了复合材料的界面结合性能。更多还原

【Abstract】 Diethynylbenzene, a kind of po]yarylacetylene(PAA) monomers, can be grafted onto the surface of the carbon fiber by plasma technology. Interlaminar.sbear strength (ILSS) of the CF/PAA composites were measured and compared with at different treating conditions. The results show that the ILSS of the composites are improved greatly. The values of ILSS are determined at many treatment conditions, such as treatment time, treatment current and the resin content. SEM photographs of destroyed cross section of the CF/PAA composites show that the interface of carbon fiber and PAA resin are adhered tightly. The properties of CF/PAA composite interface are improved.更多还原
