Interfacial improvement of carbon fiber/polyoxymethylene composites by depositing functionalized carbon nanotubes on the fibers

Zhu, Quping

Abstract

CF/POM/CNT ternary composites have been prepared by melt blending method with carbon nanotubes (CNT) asmodifier, maleic anhydride (MAH) as interfacial compatibilizer and polyoxymethylene (POM) as matrix. The mechanicalproperties of CNT on CF/POM have been studied by temperature-controlled tensile, and scanning electron microscopyanalysis. The results show that the interface properties of CF/ POM/CNT ternary composites can be improved by addingMAH, thus improving the mechanical properties of the composites. The tensile strength, bending strength and impactstrength of the ternary composite at room temperature have increased, and the tensile strength of CF/POM/CNT ternarycomposites has improved by 12.1%.
