Abstract

The majority of research on carbon fibers in concrete has focused on short, discontinuous fibers. These fibers can be effective in bridging small surface cracking, but typically do not produce significant gains in flexural strength. The current research focuses on long (7.5cm) carbon fiber tape that is reengineered with a proprietary coating process. This proprietary process may also be used to reengineer certain waste materials used in the aerospace industry. By utilizing this process, the fibers can be well dispersed in the concrete matrix and good workability is retained. In static testing the fibers have significantly increased the tensile strength of concrete specimens and show potential for replacing all or a portion of the traditional reinforcement in some applications. The ductility and failure behavior of the long fiber reinforced specimens under static load suggests impact resistance as a promising application for this material. The impact testing program is underway and preliminary results are presented.
