The morphological and compositional changes of the PP fibers pretreated with dielectric barrier discharge (DBD) are investigated with SEM, XPS and IR. The result shows that the etching effect is the main reason for the improvement of the result of pull-out test of the fiber-cement composite reported in a previous paper and the oxidation of the fiber surface also favors the adhesion between the fiber and the matrix. 相似文献

The effect of dielectric barrier discharge(DBD)on the interfacial mechanical property of polypropylene fiber reinforced cement is investigated with the aid of single fiber pull out test.The result shows that the DBD treatment improved the adhesion between the PP fiber and the surrounding cement matrix considerably without serious aging.Keywords:dielectric barrier discharge,single fiber pull-out test. 相似文献
