摘要：利用单丝临界断裂长度法研究了玻璃纤维（ＧＦ）与聚丙烯（ＰＰ）的界面结合，发现在纤维与基体均未作任何处理以前，ＰＰ与ＧＦ的界面剪切强度（ＩＳＳ）只有２．７５ＭＰａ。在ＧＦ经偶联剂处理情况下，若在ＰＰ中加入０．３％不饱和芳香酰亚胺，ＩＳＳ增至４．４２ＭＰａ提高６０％。酸酐改性ＰＰ的使用，可使ＩＳＳ达９．２０ＭＰａ，提高２３３．９％。这一方法不仅可以准确判断ＰＰ与ＧＦ界面结合的优劣。
With the analysis method of the critical fragment length of a single fiber, the interfacial bonding of glass fiber (GF) with polypropylene (PP) is researched. It is found that the interfacial shear strength(ISS) of PP matrix with untreated GF only amounts to 2.75 MPa. However, on the basis of pretreatment of glass fibers with suitable coupling agent,if the fibers are further treated with bismaleimide(BMI), ISS of the composite can be enhanced to 4.42 MPa (increasing by 60%). By blending PP matrix with the anhydride grafted PP (MPP), ISS of the composite can be enhanced to 9.20 MPa (increasing by 233.9 %). With the analysis method,not only can it be accurately determined,whether the interfacial bonding of PP with GF is stronger or weaker,but also can the reliable basis be provided for the design of the final composite.
