Effective treatments for enhancing carbon fiber/epoxy interfacial properties and carbon yarn weavability

Carbon fiber-reinforced polymer composites have wide applications in the automotive, aerospace and construction industries, etc. However, due to the chemically inert surface of carbon fiber, interfacial problems always exist when the carbon fiber is infiltrated by the resin. In this study, polypyrrole (PPy) and carbon nanotubes (CNTs) were deposited on the carbon fiber surface in order to improve the interfacial properties between the carbon...
