摘　　要：对ABS/长玻璃纤维(LGF)及ABS/LGF/SMA(苯乙烯/马来酸酐共聚物)2种复合材料的界面形态、纤维效率系数和力学行为进行了研究。结果表明:界面粘结作用是影响力学性能和纤维效率系数的关键因素。对于ABS/LGF体系,弱的界面相互作用使材料表现出低的力学性能和纤维效率系数。而对于ABS/LGF/SMA体系,由于纤维和基体树脂之间的界面相互作用增强导致材料呈现出更高的力学强度,同时纤维效率系数也得到提高。The interracial adhesion, fiber efficiency factors and mechanical properties of ABS/LGF and ABS/ LGF/SMA composites were investigated. The results showed the interracial bonding was a decisive cause to influence the mechanical properties and fiber efficiency factors. In ABS/LGF composite, the weak fiber and matrix adhesion resulted in inferior mechanical properties and lower fiber efficiency. Whereas ABS/ LGF/SMA composite had enhanced interfacial adhesion which made the composite superior mechanical properties by adding of SMA, corresponding fiber efficiency factors were also improved.
