采用基本断裂功（EWF）法研究了玻璃微珠（GB）粒径和含量对GB填充线性低密度聚乙烯（LLDPE）复合材料断裂行为的影响。结果表明，复合材料的比EWF（we）低于纯LLDPE的比EWF（we），并且对于具有不同GB直径的填充样品，所获得的we值没有显示出显著差异。非EWF或塑性功（βwp）也随着GB的加入而降低，表明对于填充有不同直径GB的复合材料，在断裂过程中吸收的能量较少。对于不同含量的GB填充的复合材料，随着GB含量的增加，βwp减小，在较低含量时，βwp大于纯LLDPE，随着GB含量的增加，βwp也减小。© 2005 Wiley Periodicals，Inc.应用聚合物科学杂志98：1781-1787，2006
The effect of the glass bead (GB) size and bead content on the fracture behavior of GB-filled linear low-density polyethylene (LLDPE) composites was evaluated by means of the essential work of fracture (EWF). The results indicated the specific EWF (we) is lower for the composites than that of pure LLDPE and the obtained we values do not show significant differences for the filled samples with different GB diameters. The non-EWF or plastic work (βwp) also decreased with the addition of GBs, indicating that less energy is absorbed during the fracture process for the composites filled with different diameter GBs. For the composites filled with GBs of different contents, the we decreased with increasing GB contents and the βwp that was higher than that of pure LLDPE at relatively low contents also decreased with the content of GBs. © 2005 Wiley Periodicals, Inc.
