INFLUENCE OF CARBON NANOFIBER SURFACE CHARACTERISTICS ON COMPOSITE PROPERTIES

摘要

Carbon nanofibers (CNF) are vapor grown carbon fibers grown catalytically from gaseous hydrocarbons using metallic catalyst particles. Good adhesion between these fibers and matrix resins is essential for the performance of CNF based composites, so the mechanical properties of composites are strongly influenced by fiber surface morphology and chemistry. This presentation examines the fiber-matrix adhesion problem as influenced by CNF fiber surface area and energy. It will be shown that optimal fiber surface areas and energies for providing significant reinforcement in PP composites can be defined. In addition the influence of the fiber surface on electrical properties of selected organic matrix composites will be discussed.
