摘    要:为提高PBO纤维/环氧树脂的剪切强度,采用聚合物涂层法对PBO纤维进行表面改性。通过NOL环复合材料层间剪切强度测试,研究不同浓度的表面涂层处理液、不同浸渍工艺对复合材料层间剪切强度的影响。结果表明:PBO纤维表面经不同涂层处理液处理后,层间剪切强度均高于未经表面处理的;当PBO纤维经过以涂层A为一浴浸渍液、涂层B为二浴浸渍液的两次浸渍工艺处理后,层间剪切强度最高,比未经表面处理的提高了61%。

关 键 词:PBO纤维  PBO纤维/环氧树脂复合材料  表面处理  层间剪切强度

Abstract:This article studies the surface modification of PBO fiber by using the polymer coating method. The
impact of surface coating treatment liquor with different concentration and different impregnation process on interlaminar shear strength of the composite materials is investigated through NOL ring interlamminar shear strength test. The results show that the treatment of surface through coating method can increase composite interlaminar shear strength.When the PBO fiber surface after the treatment of twice impregnation process,the efficiency is most obvious. The interlaminar shear strength up to 61% higher than that of the fiber without surface treatment.
Keywords:PBO fiber  PBO fiber/ epoxy resins composite  Surface modification  Interlaminar shear strength
